如何使用jQuery锚点设置文本框的值? [英] How do I set a textbox's value using an anchor with jQuery?

问题描述

我有一个文本框，我想根据锚标签的内部文本设置其值.换句话说，当有人点击该锚点时:

I have a textbox whose value I want to set based on the inner text of an anchor tag. In other words, when someone clicks on this anchor:

<a href="javascript:void();" class="clickable">Blah</a>

我希望我的文本框填充文本"Blah".这是我当前正在使用的代码:

I want my textbox to populate with the text "Blah". Here is the code I am currently using:

<script type="text/javascript">
    $(document).ready(function(){
        $("a.clickable").click(function(event){
            $("input#textbox").val($(this).html());
        });  
    });
</script>

在我的html中，有一个锚标签列表，其中包含"clickable"类和一个ID为"textbox"的文本框.

And in my html there is a list of anchor tags with the class "clickable" and one textbox with the id "textbox".

我已经用代码替换了上面的代码，以仅显示带有$(this).html()的javascript警报，并且它似乎显示了正确的值.我也将$(this).html()更改为硬编码字符串，并正确设置了文本框值.但是，当我将它们组合在一起时，文本框就被清除了.我在做什么错了?

I've substituted the code above with code to just show a javascript alert with $(this).html() and it seems to show the correct value. I have also changed the $(this).html() to be a hardcoded string and it setes the textbox value correctly. But when I combine them the textbox simply clears out. What am I doing wrong?

推荐答案

我编写了此代码段，效果很好:

I wrote this code snippet and it works fine:

<a href="#" class="clickable">Blah</a>
<input id="textbox">
<script type="text/javascript">
    $(document).ready(function(){
        $("a.clickable").click(function(event){
            event.preventDefault();
            $("input#textbox").val($(this).html());
        });  
    });
</script>

也许您忘记为链接指定一个可点击"的类名了?

Maybe you forgot to give a class name "clickable" to your links?
