anything that you tried so far ? .

on way i believe to do his would be to use an object literal something like

myObj = {
'a' : 1,
'b' : 2
}

and then run it through an $.each() function , like so:

$.(myObj , function(i , e){
// check if the value matches and replace or do whatever you want :D
});

I searched and finaly made this, that works fineeee:

String.prototype.allReplace = function (obj) {

var retStr = this;

for (var x in obj) {

retStr = retStr.replace(new RegExp(x, 'g'), obj[x]);

}

return retStr;

};

$("*").each(function () {

var el = $(this);

if (el.children().length == 0) {

el.text(el.text().allReplace({ "0": "a", "1": "b", "2": "c"}));

}

});

Make a new regular expression out of x. (x is 0,1,2).

Replace all occurences of it with obj[x] (a,b,c)

Do you need to learn regular expressions ?

It's weird to everyone!

MDN is a great reference for all things HTML/CSS/Javascript:

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/RegExp

Use your desktop browser's Javascript Console to easily experiment by typing-in expressions and immediately seeing the result.

See if you can figure out why

String.prototype.allReplace = function (obj) {
var retStr = this;
for (var x in obj) {
retStr = retStr.replace(new RegExp("\\b"+x+"\\b", 'g'), obj[x]);
}
return retStr;
};

is a better version. Hint: it's the \b.

Try it with

"foo bar foobar".allReplace({foo:"Jake","bar":"dog"})
