I got a li
that looks like:
<li temp="true">HELLO</li>
How would I get "temp" so I can manipulate "HELLO" in JS...I know how by id or even className
In supporting browsers (that is, anything except ancient IE):
var li = document.querySelector("li[temp=true]");
If support for older IE is required try this:
var li = document.querySelector ? document.querySelector("li[temp=true]")
: (function() {
var lis = document.getElementsByTagName('li'), l = lis.length, i;
for( i=0; i<l; i++) {
if( lis[i].getAttribute("temp") == "true") return lis[i];
}
return false;
})();
In jQuery, you can use the attribute selector:
$('li[temp="true"]');
Alternatively, you can use the document.querySelectorAll()
method for a native JS solution. You should be aware of the cross-browser implications of this, however:
var ele = document.querySelectorAll('li[temp="true"]');
You can see a jsFiddle Demo of the above.
As an aside, you should use data-
attributes to store custom attributes with HTML elements, for example the correct syntax should be:
<li data-temp="true">HELLO</li>
Iterate through all li.
var li = document.getElementsByTagName("li");
var found;
for(var i=0; i< li.length;i++){
if(li[i].getAttribute("temp") == "true"){
found = li[i]; break;
}
}
console.log(found);
OR You can use native query
var found= document.querySelectorAll('li[temp="true"]');
