I have a reference to a DOM 开发者_Go百科element, and a jQuery object which is the result of a selector, and I want to check if that specific DOM element is in that jQuery object. Short of looping through the whole jQuery object and checking for equality, is there a straightforward way in jQuery to do this?
I have tried .contains
, :contains
, .has
and :has
, and none of them seem to do the job. Also, I should mention that all the elements I'm working with are on the same DOM tree level, so there is no need to worry about parents/children.
$yourJqueryObject.is(yourDomElement)
See .is() added in 1.6.
similar to Gumbos answer, but slimmer:
if ( obj.filter(function() { return this == el; }).length ) {
// obj contains el
}
Try this:
var result = $("selector").find("*").filter(function() {
return this === elem;
}).length === 1;
elem
is the DOM element you are looking for.
Similar to David's answer but even slimmer:
if ( obj.filter(el).length ) {
// obj contains el
}
Kinda hackish, but works for me:
$.inArray($('#single-element').get(0), $('.many-elements').get()) != -1
