$('#myform :checkbox').click(function() {
var $this = $(this);
// $this will contain a reference to the checkbox
if ($this.is(':checked')) {
// the checkbox was checked
} else {
// the checkbox was unchecked
}
});
Where your form has id myform
您的表单有 id 的地方 myform

First of all, there's a mistake. It should be .is(":checked").
首先，有一个错误。应该是.is(":checked")。
function check(cb)
{
if($(cb).is(":checked"))
{
//my functionality and operations
}
}
And the HTML should be:
并且 HTML 应该是：
<input type="checkbox" onclick="check(this);" />
Or, if you wanna invoke a PHP Function after clicking on Checkbox, you need to write an AJAX code. If this is the case, in your ifcondition, and checked condition, you can call a PHP file, that calls only this function.
或者，如果您想在单击 Checkbox 后调用 PHP 函数，则需要编写 AJAX 代码。如果是这种情况，在您的if条件和检查条件下，您可以调用仅调用此函数的 PHP 文件。
function check(cb)
{
if($(cb).is(":checked"))
{
$.getScript("clickCheckbox.php");
}
}
And you can write JavaScript plus PHP in the clickCheckbox.phpfile, say something like this:
你可以在clickCheckbox.php文件中编写 JavaScript 和 PHP ，这样说：
clickCheckbox.php
clickCheckbox.php
<?php
header("Content-type: text/javascript");
unlink("delete.png");
echo 'alert("Deleted!");';
?>
Once you click on the checkbox, and if the state is checked, it gives out an AJAX call to this PHP file, where you are deleting a file delete.pngand in the echostatement, you are outputting a JavaScript alert, so that you will get an alert message saying Deleted!.
单击复选框后，如果状态为checked，它会向此 PHP 文件发出 AJAX 调用，您将在其中删除文件，delete.png并在echo语句中输出 JavaScript 警报，以便您收到警报消息说Deleted!。

use
用
if ($('#checkbox').is(':checked'))
or inside an event
或在事件内
$('#checkbox').click(function(){
if ($(this).is(':checked')){
//your routine here if checked
}else{
//routine here if not checked
}
});

Try this one
试试这个
<input id="checkbox" name="click" type="checkbox" onclick="check()"/>
//in js
if( $('input[name=checkbox]').is(':checked') ){
// your code
}
