Menu
I need to replace some part of text, e.g. mustache var {{myvar}}, on already loaded page. Example html:
<html>
<head>
<title>{{MYTITLE}}</title>
</head>
<body>
<p><strong><ul><li>text {{TEXT}}</li></ul></strong></p>
{{ANOTHER}}
</body>
</html>
$(html).html(myrenderscript($(html).html()))!It's ugly, slow and brokes <script> tags.
I want to get closest tag with {{}} and than render and replace.
Firstly, i tried: $('html :contains("{{")). But it returns <title>, <p>, <strong> .... But i need <title> and <li>.
Than i tried to filter them:
$('html :contains("{{")').filter(function (i) {
return $(this).find(':contains("{{")').length === 0
});
...but it WONT return {{ANOTHER}}. And that is my dead end. Your suggestions?

Using http://benalman.com/projects/jquery-replacetext-plugin/ you could do the following:
$('html *').replaceText(/{{([^}]+)}}/, function(fullMatch, key) {
return key;
}, true);

If all you want to do is replace that text - then surely the following works (or have I mis-understood)
usage is as follows: CONTAINER (body) - replaceTExt (search term (I have built the function to always include {{}} around the term), (replace - this will remove the {{}} as well)
$('body').replaceText("MYTITLE","WHATEVER YOU WANT IT REPLACING WITH");
$.fn.replaceText = function(search, replace, text_only) {
return this.each(function(){
var v1, v2, rem = [];
$(this).find("*").andSelf().contents().each(function(){
if(this.nodeType === 3) {
v1 = this.nodeValue;
v2 = v1.replace("{{" + search + "}}", replace );
if(v1!=v2) {
if(!text_only && /<.*>/.test(v2)) {
$(this).before( v2 );
rem.push(this);
}
else this.nodeValue = v2;
}
}
});
if(rem.length) $(rem).remove();
});
};
