失败后插入的每个循环 [英] each loop for insertafter failing

问题描述

我试图在每个<label class="control-label">之后添加<span class='validation'></span>.我尝试了以下方法，但是它在每个标签之后多次添加了span类.

I am trying to add <span class='validation'></span> after each <label class="control-label">. I have tried following but it's adding span class multiple times after each label.

我还尝试在控件标签类之后使用.one()，但是没有用.

I have also tried using .one() after control label class but didn't worked.

我也想为每个选择添加相同的类.将在$('#myform :input')内添加选择有效吗?

I want to add same class for each select as well. will adding select inside $('#myform :input') work?

此代码出了什么问题.

$('#myform :input').each(function(){
    $( "<span class='validation'></span>").insertAfter(".control-label");                           
});

HTML

<div class="col-sm-12">
     <label for="Rec_Name" class="control-label">Your Name :</label>    
     <input class="form-control" type="text" id="Rec_Name" name="Rec_Name" placeholder="Enter Your Name">
</div>

推荐答案

因为您在每个控件标签类之后添加了span.

Because you add span to after each control-label class.

尝试这样:

$('<span>Validation</span>').insertAfter($(this).parent().find('.control-label'));

也许有点疯狂，但应该可以工作. 希望这会有所帮助.

Maybe a little crazy but should work. Hope this helps.
