通过JS为HTML标签添加样式

1、直接根据id赋予类或移除类；

<style>
    .tab-close{
        cursor: not-allowed;
    }
    .atab-close{
        pointer-events: none;
    }
</style>

<li id="tab2"><a id="atab2" href="#tab_2" data-toggle="tab">1</a></li>

//js代码
<script>
    $("#tab2").addClass("tab-close");
    $("#atab2").addClass("atab-close");
    $("#tab2").removeClass("tab-close");
    $("#atab2").removeClass("atab-close");
</script>

2、动态为元素赋予类或移除类

var element = document.getElementById(ys_id);
element.classList.add("focusColor");//给ys_id添加类focusColor的样式
element.parentNode.classList.add("focusColor");//给ys_id的父元素添加类focusColor的样式

View Code

3、select2中设置下拉框的样式

$('#ylfkfs').select2({
            data:${ylfkfs},
            language : "zh-CN",
            multiple:false,
            minimumResultsForSearch: -1
        });
        var span_select = document.getElementById("select2-ylfkfs-container").parentNode;
        span_select.style.border = "0px";
        document.getElementById("select2-ylfkfs-container").style.paddingLeft = "13px";
