如何集体改变对象的类型？

Question

I have different number objects such as a = 1, b = 2. I want to use iterate method to change them into jQuery objects as followings

var a = 1, b = 2;
var ArrayToJQuery = [a, b];

for (var obj in ArrayToJQuery) {
    obj = $("<div>").text(obj);
}

a.click(function(){ alert($(this).text())}); //error

I have tried for, forin, forEach. None of them works. How can I achieve that?

Answer 1

For this sort of thing, it's best to use object properties rather than variables:

var stuff = {
    a: 1,
    b: 2
};
var key;
for (key in stuff) {
    stuff[key] = $("<div>").text(stuff[key]);
}

Instead of the for-in you could use jQuery's $.each :

var stuff = {
    a: 1,
    b: 2
};
$.each(stuff, function(key, entry) {
    stuff[key] = $("<div>").text(entry);
});

Answer 2

you can use jquery .each for this.

$.each([ 52, 97 ], function( index, value ) { alert( index + ": " + value );});
