I stumbled upon this form of selector. Notice the quotes, its two attributes.
$('#item1','#item2')
It seems to return only first element, which is different from $('#item1, #item2') result. I couldn't find any documentation on what exactly this does. Can somebody explain this or link to documentation with examples please
It's called context, and it's the same as find(), so this:
$('#item1','#item2')
would equal :
$('#item2').find('#item1');
in other words, it searched inside #item2 for an element with the ID #item1
To select both elements with ID's #item1 and #item2, you would do:
$('#item1, #item2')
notice the difference in quotes.
search #item1 in #item2.
#item2 that matched the ID #item1.Selector in Jquery $(param) supports single string parameter and then it split parameter string and then do work for selecting element..
$('#item1','#item2') //treat first one param
$('#item1,#item2') //treat one param and splits passed string and will select both
You can specify any number of selectors to combine into a single result.
This multiple expression combinator is an efficient way to select disparate elements.
multiple-selector
multiple-selector-2
var list = $("div,p,span").map(function () {
return this.tagName;
}).get().join(", ");
$("b").append(document.createTextNode(list));
