element creation with templates [ 1225 views ]
Goal: to create a quick template based element creation method
Everyday task to manage item templates. We have a container <div id="cont"></div> and the template of the items.
var tmp = '<div id="%id%" value="%value%">%obj%</div>',
itms = [{id: 1, value: 'val1', obj: 'first'},{id: 2, value: 'val2', obj: 'second'}];
console.log(tmp.template(itms));
or
$('#cont').html(tmp.template(itms));
the result will be:
<div id="1" value="val1">first</div><div id="2" value="val2">second</div>
to achieve this we have to extend the String object with a template function:
TypeExtend(String, 'template', function(data) {
if(data instanceof Array){
var ret = '';
for(i in data){
ret += this.template(data[i]);
}
return ret;
}
else{
return this.replace(/%(\w*)%/g, function(m, key) { return data.hasOwnProperty(key) ? data[key] : ""; });
}
});
the TypeExtend function itself is here: jump
