Find and replace all matching dynamic strings using jquery or javascript -
here body of html:
<body> <div>_good morning john... _welcometext.</div> <label> _welcometext </label> <a href="">_good</a> </body> here jquery:
var custom_obj = {}; custom_obj["_welcometext"] = "welcome in custom"; custom_obj["_good"] = "good in custom"; $.each(custom_obj, function(key, value) { $('body').text(function(index,text){ return text.replace(key,value); }); }); this code works replaces 1st instance of matched pattern. replacing key dynamic value coming foreach loop, not able use /key/g replace instances. please help.
i not recommend text based operation that
important, costly
var custom_obj = {}; custom_obj["_welcometext"] = "welcome in custom"; custom_obj["_good"] = "good in custom"; var $contents = $('body *').addback().contents(); $.each(custom_obj, function (key, value) { var regex = new regexp(key, 'g'); $contents.each(function () { if (this.nodetype == 3) { this.nodevalue = this.nodevalue.replace(regex, value); } }) }); demo: fiddle
