WebApp开发-Zepto
作者：互联网
zepto.js自己去官网下载哈。
DOM操作
$(document).ready(function(){
var $cr = $("<div class='cr'>插入的div</div>");
// 插入操作
$("#a").append($cr);
$cr.appendTo($("#a"));
$("#a").prepend($cr);
$cr.prependTo($("#a"));
$("#a").after($cr);
$cr.insertAfter($("#a"));
$("#a").before($cr);
$cr.insertBefore($("#a"));
// 删除 remove\empty
$("ul li").remove();
$("ul li").empty();
// 复制节点
$("ul li").click(function(){
$(this).clone().appendTo("ul");
});
// 替换节点 replaceWith
$("p").replaceWith("<span>是的，哈哈</span>");
// 包裹节点 wrap wrapAll
$("p").wrap("<div></div>");
$("p").wrapAll("<div></div>");
});
属性与样式操作
$(document).ready(function(){
// 属性操作 attr("title") attr("name","att") attr({"name":"att" , "class":"test"}) removeAttr("title name")
console.log($("div").attr("title"));
$("div").attr("name","att");
$("div").attr({"name":"att" , "class":"test"})
$("div").removeAttr("title name");
// 添加样式操作 addClass
$("div").addClass("red").addClass("fs");
$("div").addClass("red fs");
// 删除class类 removeClass
$("div").removeClass();
// 切换样式 toggle toggleClass
$("button").click(function(){
$("div").toggle(); // show和hide的切换
$("div").toggleClass("red"); // addClass("red")和removeClass("red");
});
// 判断是否含有某个样式 hasClass
console.log($("div").hasClass("red fs"))
});
遍历节点
$(document).ready(function(){
// next是取得紧邻的后面的同辈元素
console.log($("#one h3").next());
// prev获取紧邻的前面的同辈元素
console.log($("#one a").prev());
// siblings获取前后的所有同辈元素
console.log($("#one p").siblings());
// parent与parents直系亲属
console.log($("b").parent());
console.log($("b").parents());
});
CSS-DOM操作
$(document).ready(function(){
$(".one").css("color", "red").css("fontSize", "36px");
$(".one").css({
color:"red",
fontSize:"36px"
});
$(".one").width(500);
$(".one").height(500);
});
ready与onload的区别
// html文件 、 css文件 、 js文件 、 图片文件等
$(document).ready(function(){
// DOM加载完毕，图片并未完全加载，调用时机比较快
});
window.onload = function(){
// 全部文件加载完毕，调用时机比较久
}
事件开头简写
$(document).ready(function(){
})
$(function(){
})
$().ready(function(){
})
事件绑定
$(".one").bind("click", function(e){
console.log("one被点击了！！！")
})
$(".one").click(function(e){
console.log("我是简写方式");
})
$(".one").on("click", function(e){
console.log("我是on事件");
});
---------------------------------
// on
$("ul").on('click', 'li', function(e){
})
// off
$("li").off();
zepto不支持事件捕获
事件其他用法
// 自定义事件
$("div").bind("muke", function(){
console.log("触发自定义事件");
});
$("div").trigger("muke");
// 命名空间
$("div").bind("click", function(){
console.log("我是普通的click事件");
})
$("div").bind("click.muke", function(){
console.log("我是click.muke的事件");
})
$("div").unbind(".muke");
// 绑定多个事件
$("div").bind("click", function(){
console.log(111)
}).bind("touchstart", function(){
console.log(222)
})
动画
$('button').on('click' , function(){
$('div').toggle('slow'); //切换元素的显示与隐藏
$('div').hide(3000);
$('div').show('slow');
$('div').fadeIn('slow');
$('div').fadeOut('slow');
$('div, button').fadeToggle('slow');
$("div").fadeTo(3000 , 1)
})
animate() 动画函数
$("div").animate({left:"300px", height:"300px"}, 3000, function(){
alert("动画执行完毕");
})
Ajax
function Ajax(){
var xmlHttpReq = null;
if(window.ActiveXObject){
// 兼容IE5、IE6
xmlHttpReq = new ActiveXObject("Microsoft.XMLHTTP");
}else{
xmlHttpReq = new XMLHttpRequest();
}
xmlHttpReq.open("GET", "test.php", true);
xmlHttpReq.onreadystatechange = RequestCallBack;
function RequestCallBack(){
if(xmlHttpReq.readyState == 4){
if(xmlHttpReq.status == 200){
console.log("获取数据："+xmlHttpReq.responseText);
}
}
}
xmlHttpReq.send(null);
}
ajax请求
// get
$.get('urlxxx',function(response){
$(document.body).append(response)
});
// post
$.post('urlxxx', { sample: 'payload' }, function(response){
});
// ajax
$.ajax({
type: 'GET',
url: 'urlxxx',
data: { name: 'Zepto.js' },
dataType: 'json',
success: function(data){
this.append(data.project.html)
},
error: function(xhr, type){
alert('Ajax error!')
}
})
touch模块
先引入touch.js
<script type="text/javascript" src="../../lib/touch.js"></script>
touch.js
;(function($){
var touch = {},
touchTimeout, tapTimeout, swipeTimeout, longTapTimeout,
longTapDelay = 750,
gesture
function swipeDirection(x1, x2, y1, y2) {
return Math.abs(x1 - x2) >=
Math.abs(y1 - y2) ? (x1 - x2 > 0 ? 'Left' : 'Right') : (y1 - y2 > 0 ? 'Up' : 'Down')
}
function longTap() {
longTapTimeout = null
if (touch.last) {
touch.el.trigger('longTap')
touch = {}
}
}
function cancelLongTap() {
if (longTapTimeout) clearTimeout(longTapTimeout)
longTapTimeout = null
}
function cancelAll() {
if (touchTimeout) clearTimeout(touchTimeout)
if (tapTimeout) clearTimeout(tapTimeout)
if (swipeTimeout) clearTimeout(swipeTimeout)
if (longTapTimeout) clearTimeout(longTapTimeout)
touchTimeout = tapTimeout = swipeTimeout = longTapTimeout = null
touch = {}
}
function isPrimaryTouch(event){
return (event.pointerType == 'touch' ||
event.pointerType == event.MSPOINTER_TYPE_TOUCH)
&& event.isPrimary
}
function isPointerEventType(e, type){
return (e.type == 'pointer'+type ||
e.type.toLowerCase() == 'mspointer'+type)
}
$(document).ready(function(){
var now, delta, deltaX = 0, deltaY = 0, firstTouch, _isPointerType
if ('MSGesture' in window) {
gesture = new MSGesture()
gesture.target = document.body
}
$(document)
.bind('MSGestureEnd', function(e){
var swipeDirectionFromVelocity =
e.velocityX > 1 ? 'Right' : e.velocityX < -1 ? 'Left' : e.velocityY > 1 ? 'Down' : e.velocityY < -1 ? 'Up' : null
if (swipeDirectionFromVelocity) {
touch.el.trigger('swipe')
touch.el.trigger('swipe'+ swipeDirectionFromVelocity)
}
})
.on('touchstart MSPointerDown pointerdown', function(e){
if((_isPointerType = isPointerEventType(e, 'down')) &&
!isPrimaryTouch(e)) return
firstTouch = _isPointerType ? e : e.touches[0]
if (e.touches && e.touches.length === 1 && touch.x2) {
// Clear out touch movement data if we have it sticking around
// This can occur if touchcancel doesn't fire due to preventDefault, etc.
touch.x2 = undefined
touch.y2 = undefined
}
now = Date.now()
delta = now - (touch.last || now)
touch.el = $('tagName' in firstTouch.target ?
firstTouch.target : firstTouch.target.parentNode)
touchTimeout && clearTimeout(touchTimeout)
touch.x1 = firstTouch.pageX
touch.y1 = firstTouch.pageY
if (delta > 0 && delta <= 250) touch.isDoubleTap = true
touch.last = now
longTapTimeout = setTimeout(longTap, longTapDelay)
// adds the current touch contact for IE gesture recognition
if (gesture && _isPointerType) gesture.addPointer(e.pointerId)
})
.on('touchmove MSPointerMove pointermove', function(e){
if((_isPointerType = isPointerEventType(e, 'move')) &&
!isPrimaryTouch(e)) return
firstTouch = _isPointerType ? e : e.touches[0]
cancelLongTap()
touch.x2 = firstTouch.pageX
touch.y2 = firstTouch.pageY
deltaX += Math.abs(touch.x1 - touch.x2)
deltaY += Math.abs(touch.y1 - touch.y2)
})
.on('touchend MSPointerUp pointerup', function(e){
if((_isPointerType = isPointerEventType(e, 'up')) &&
!isPrimaryTouch(e)) return
cancelLongTap()
// swipe
if ((touch.x2 && Math.abs(touch.x1 - touch.x2) > 30) ||
(touch.y2 && Math.abs(touch.y1 - touch.y2) > 30))
swipeTimeout = setTimeout(function() {
if (touch.el){
touch.el.trigger('swipe')
touch.el.trigger('swipe' + (swipeDirection(touch.x1, touch.x2, touch.y1, touch.y2)))
}
touch = {}
}, 0)
// normal tap
else if ('last' in touch)
// don't fire tap when delta position changed by more than 30 pixels,
// for instance when moving to a point and back to origin
if (deltaX < 30 && deltaY < 30) {
// delay by one tick so we can cancel the 'tap' event if 'scroll' fires
// ('tap' fires before 'scroll')
tapTimeout = setTimeout(function() {
// trigger universal 'tap' with the option to cancelTouch()
// (cancelTouch cancels processing of single vs double taps for faster 'tap' response)
var event = $.Event('tap')
event.cancelTouch = cancelAll
// [by paper] fix -> "TypeError: 'undefined' is not an object (evaluating 'touch.el.trigger'), when double tap
if (touch.el) touch.el.trigger(event)
// trigger double tap immediately
if (touch.isDoubleTap) {
if (touch.el) touch.el.trigger('doubleTap')
touch = {}
}
// trigger single tap after 250ms of inactivity
else {
touchTimeout = setTimeout(function(){
touchTimeout = null
if (touch.el) touch.el.trigger('singleTap')
touch = {}
}, 250)
}
}, 0)
} else {
touch = {}
}
deltaX = deltaY = 0
})
// when the browser window loses focus,
// for example when a modal dialog is shown,
// cancel all ongoing events
.on('touchcancel MSPointerCancel pointercancel', cancelAll)
// scrolling the window indicates intention of the user
// to scroll, not tap or swipe, so cancel all ongoing events
$(window).on('scroll', cancelAll)
})
;['swipe', 'swipeLeft', 'swipeRight', 'swipeUp', 'swipeDown',
'doubleTap', 'tap', 'singleTap', 'longTap'].forEach(function(eventName){
$.fn[eventName] = function(callback){ return this.on(eventName, callback) }
})
})(Zepto)
使用时：
<script>
$(document).ready(function(){
$('#touch_test').bind('touchmove', function(e) { e.preventDefault() })
listen_to('#touch_test')
function listen_to(el) {
$(el).tap(function(){
console.log(' | tap!')
})
.doubleTap(function(){
console.log(' | double tap!')
})
.swipe(function(){
console.log(' | swipe!')
})
.swipeLeft(function(){
console.log(' | swipe left!')
})
.swipeRight(function(){
console.log(' | swipe right!')
})
.swipeUp(function(){
console.log(' | swipe up!')
})
.swipeDown(function(){
console.log(' | swipe down!')
})
.longTap(function(){
console.log(' | long tap!')
})
.singleTap(function(){
console.log(' | single tap!')
})
}
});
</script>
插件的写法
先编写自定义插件js文件
zepto.color.js
;(function($){
//一个插件的写法
$.fn.color = function(option){
var options = $.extend({
col: "blue",
fz : "20px"
}, option);
this.css("color", options.col);
this.css("fontSize", options.fz);
return this;
}
})(Zepto);
//多组插件写法
/*
;(function($){
$.extend($.fn, {
color: function(option){
var options = $.extend({
col: "blue",
fz : "20px"
}, option);
this.css("color", options.col);
this.css("fontSize", options.fz);
return this;
},
background: function(option){
var options = $.extend({
bg: "blue"
}, option);
this.css("background", options.bg);
return this;
}
})
})(Zepto);
*/
使用时：
<script type="text/javascript" src="../../lib/zepto.color.js"></script>
<script type="text/javascript">
$("div").color({
col : "red"
}).addClass("helloworld");
</script>
