javascript-将SELECT-OPTIONS文本右对齐

这些是我正在开发的表单的屏幕截图.

我要设计表单中的选择框,以使选项中的文本右对齐,并且在选择选项后,所显示的所选文本也应显示如下图所示.

HTML代码：

<select>
    <option value="0" selected="selected" style="text-align: right;">EqualsTo</option>
    <option value="1">LessThan</option>
    <option value="2">GreaterThan</option>
    <option value="3">LessThanEqualsTo</option>
    <option value="4">GreaterThanEqualsTo</option>
    <option value="5">Between</option>
</select>

解决方法:

尝试这个.

HTML

<select id="mySelect" dir="rtl">
    <option value="0" selected="selected" >EqualsTo</option>
    <option value="1">LessThan</option>
    <option value="2">GreaterThan</option>
    <option value="3">LessThanEqualsTo</option>
    <option value="4">GreaterThanEqualsTo</option>
    <option value="5">Between</option>
</select>

JS

function InitializeSelect(elem) {
    $("#" + elem).each(function () {
        $(this).wrap('<div class="selectbox"/>');
        $(this).after("<span class='selecttext'></span><span class='select-arrow'></span>");
        var val = $(this).children("option:selected").text();
        $(this).next(".selecttext").text(val);
        $(this).change(function () {
           var val = $(this).children("option:selected").text();
           $(this).next(".selecttext").text(val);
       });
       var selectId = $(this).attr('id');
          if (selectId !== undefined) {
           var linkClass = selectId;
       }
       if (linkClass) {
           $(this).parent('.selectbox').addClass(linkClass);
       }
   });
}

$(document).ready(function(){
    InitializeSelect('mySelect');
});
