JS提交表单页面不跳转、JS下载、动态创建from

JS下载

function downloadFile(id) {
 
    var url =  "<%=request.getContextPath()%>/cer/downloadFile";
    var form = $("<form></form>").attr("action", url).attr("method", "post");
    form.append($("<input></input>").attr("type", "hidden").attr("name", "fileId").attr("value", id));
    form.appendTo('body').submit().remove();//提交之后再删除from表单
   
}

动态创建from，提交表单

jForm.appendTo('body')
function loadPage(url, projectName) {
    var jForm = $('<form></form>', {
        action: url,
        method: 'post'
    });
 
    $("<input>", {
        name: 'curPrj',
        value: projectName
    }).appendTo(jForm);
 
    jForm.appendTo('body').submit();
}
 
 var form = $("<form method='post'></form>"),
        input;
    form.attr({ "action": url });
    $.each(args, function (key, value) {
        input = $("<input type='hidden'>");
        input.attr({ "name": key });
        input.val(value);
        form.append(input);
    });
    form.appendTo('body').submit();
