将点击事件绑定到我页面上的锚定标签 [英] bind click event to anchor tags on my page
问题描述
以下是我的javascript文件代码. Script.js
Below is my javascript file code. Script.js
$(document).ready(function(){
$("#").click(function(){
alert("Hello!");
});
这是我的php代码.
<html>
<head>
Some codes are here
</head>
<body>
Some php codes are here to get value from database
<script src="script.js"></script>
<span><a href="#" class="vote" id="<?php echo $cid; ?>" name="up"><i class="fa fa-thumbs-up"></i></a> <?php echo $up; ?> </span>
<span><a href="#" class="vote" id="<?php echo $cid; ?>" name="down"><i class="fa fa-thumbs-down"></i></a> <?php echo $down; ?> </span>
<span><a href="#" class="vote" id="<?php echo $cid; ?>" name="favorite"><i class="fa fa-star-o"></i></a> <?php echo $fav; ?> </span>
</body>
</html>
由于我的设计原因，我正在体内调用脚本文件.我不能在头部称呼它.
I am calling script file in body due to my design. I can't call it in head section.
问题是当我单击与#(上，下，最爱)相对应的以上链接时.我需要索引文件.我正在警报框中测试Hello.但这不起作用.
Issue is when i click on above link corresponding to # (up,down, fav). It take me to index file. I am testing Hello in alert box. But it is not working.
任何建议我想念的东西.
Any advice what i am missing.
推荐答案
$("#")中的#表示，并且id应该紧随其后.就像您的元素的ID为"myElement"一样，您会写$("#myElement").
The # in $("#") means and id should follow. Like if your element's id were "myElement" you would write $("#myElement").
但是，由于您不知道id的使用时间，id使用了已经具有的vote类，例如$(".vote").click....
But, since you dont know your ids adead of time, id use the vote class you already have instead like $(".vote").click....
$(document).ready(function() {
$(".vote").click(function(event) {
event.preventDefault();
alert("Hello! My id is: " + this.id);
});
});

<span><a href="#" class="vote" id="someId1" name="up"><i class="fa fa-thumbs-up"></i>Some sontent</a></span>
<span><a href="#" class="vote" id="someId2" name="down"><i class="fa fa-thumbs-down"></i>Some sontent</a> </span>
<span><a href="#" class="vote" id="someId3" name="favorite"><i class="fa fa-star-o"></i>Some sontent </a> </span>
