使用JQUERY更改输入名称 [英] Changing input name using JQUERY
问题描述
我正在尝试根据<li>
的列表索引更改所有输入名称,但似乎根本没有更改.
I'm trying to change all the input name based on the list index of <li>
but it seems like it's not changing at all.
$('.test').click(function() {
for(var i=0;i<$("li.songs").length;i++)
{
var ob = $("li.songs").eq(i).clone();
ob.find('input').each(function()
{
this.name = this.name+i;
alert(this.name); //just checking if does it change
});
}
});
现在,警报显示了我想要的正确名称,但是当我检查元素并尝试提交表单并显示所有POST值时,名称上没有任何更改.
Now, the alert displays the right name I want, BUT no changes on the name when I inspect the element AND try to submit the form and display all the POST values.
更改前的预期输出示例:
Example expected output before changing:
<li class="songs"><input type="text" name="song" /></li>
<li class="songs"><input type="text" name="song" /></li>
<li class="songs"><input type="text" name="song" /></li>
更改后:
<li class="songs"><input type="text" name="song1" /></li>
<li class="songs"><input type="text" name="song2" /></li>
<li class="songs"><input type="text" name="song3" /></li>
注意:我不希望输入名为song的输入成为数组.
NOTE: I DO NOT WANT the input named song to be an ARRAY.
推荐答案
您正在克隆对象,因此更改是对副本而不是原始DOM节点进行的.
You are cloning the object, so the change is done to a copy rather than the original DOM node.
不要使用clone()
,您会没事的.或执行以下操作:
Don't use clone()
and you'll be fine. Or do this:
$("li.songs input").each(function(i) {
$(this).attr('name', $(this).attr('name') + i);
});
