js method to execute string as function_javascript skills

And use js to execute:

[Ctrl A Select all Note: If you need to introduce external Js, you need to refresh to execute

]

------ --------------------------
Method 1. . .

[Ctrl A Select All Note:

If you need to introduce external Js, you need to refresh to execute
]

This is method two. . . .
The function to be executed by the checkbox is set in the value of the checkbox, and the parameter of the method is to pass the currently clicked checkbox as a parameter.

Here I use jquery to operateCopy code

The code is as follows:


$ (function() {
$("ul li a").css("cursor", "pointer");
$("ul li a").click(function() {
var $ck = $(this).siblings(":checkbox");
if ($ck.attr("name") == "total")//Select all
{
if ($ ck.attr("checked") == false) {
$ck.attr("checked", "checked");
$("[name='ck']:checkbox").attr( "checked", "checked");
var ff = $ck.val();//Get the string of the function to be executed
var cc = $ck.get(0);// Convert jquery Convert the object to a DOM object
window[ff](cc);//Execute the string function and pass the current checkbox object as a parameter
}
else {
$ck.attr(" checked", "");
$("[name='ck']:checkbox").attr("checked", "");
var ff = $ck.val();
var cc = $ck.get(0);
window[ff](cc);
}
}
else//As a choice
{
if ($ ck.attr("checked") == false) {
$ck.attr("checked", "checked");
var s = $ck.val();
var a = $ ck.get(0);
window[s](a);
}
else {
$ck.attr("checked", "");
var s = $ ck.val();
var cb = $ck.get(0);
window[s](cb);
}
}
})

})
