Send Div id to javascript via onclick
提问by richsoni
I have a page with several div's. All of the divs have a unique id. I would like to send that id to a javascript function. I have tried to save it as a value as well, and send this.value, but that does not work either.
我有一个包含多个 div 的页面。所有的 div 都有一个唯一的 id。我想将该 id 发送到 javascript 函数。我也尝试将它保存为一个值，并发送 this.value，但这也不起作用。
<div class='recordElem$val' id='$rname' value='$rname'
onclick='javascript:updateRecord(this.value);'>
$name</div>"

Have a look at two ways to solve this problem
看看解决这个问题的两种方法
<html>
<body>
<div id="scopeId" onclick="javascript:testScope.call(this)">Using scope</div>
<div id="parameterId" onclick="javascript:testId(this.id)">Using Parameter</div>
<script>
function testScope(){
alert("Scope: " + this.id)
}
function testId(id){
alert("Parameter: " + id)
}
</script>
</body>
</html>

Use onclick="updateRecord(this)"and handle it like this:
onclick="updateRecord(this)"像这样使用和处理它：
function updateRecord(div) {
// statements
var id = div.id; // or however you want to use the id
// statements
}

You can assign php variables value to javascript variable value. Then you can use it onclick example:
您可以将 php 变量值分配给 javascript 变量值。然后你可以使用它 onclick 示例：
<script language="javascript">
var a=<?php echo $tabs['menu_id']; ?>
</script>
<a href="index.php" onclick="show_center(a);">pass it</a>
Here we can pass javascript's variable to function.
在这里，我们可以将 javascript 的变量传递给函数。
