问题 Hi please look at the HTML below.

问题 I write a lot of jQuery plugins and have custom jQuery selectors I use all the time like :focusable and :closeto to provide commonly used filters. e.g. :focusable looks like this jQuery.extend(jQuery.expr[':'], { focusable: function (el, index, selector) { return $(el).is('a, button, :input[type!=hidden], [tabindex]'); }; }); and is used like any other selector: $(':focusable').css('color', 'red'); // color all focusable elements red I notice none of the jQuery selectors available can

问题 Here is the sample code which I am not able to solve. I did it using javascript, but when I am doing using jQuery, I do not able to target the element. Script : var element = window.parent.document.getElementById('iframeOne'); //this is working fine But i want to do using jQuery. So how can I target the element? 回答1: Perhaps you want to do something like this $('#iframeOne', window.parent.document); Another way to do it window.parent.$("#iframeOne"); Another way $("#iframeOne", top.document);

问题 I've got a few custom directives that use jQuery for animation effects (angular's built-in ngShow/ngHide and the like are functional, but not pretty). I think I remember reading in the documentation somewhere that angular has its own DOM selector (something like angular.export() or angular.select() ) that I should use instead of $(SELECTOR) ; however I can't find it now. I'm doing something like this: //view <div scroll-to="element"> //`element` is set via ng-click … </div> //directive link:

问题 I've starting using the Wijmo toolkit, and came across quite a few example selectors similar to this in their documentation pages: $(":input[type='radio']").wijradio(); I'd have written mine like this: $('input[type=radio]').wijradio(); Do these do the same or is there something I'm missing? Note that there are two differences above: the first selector is prefixed with a colon and has quotes for the input type. 回答1: :input is a jQuery extension while input is a CSS selector. textarea , button

问题 I recently upgraded my version of PHPStorm IDE and it now warns me about inefficient jQuery usage. For example: var property_single_location = $("#property [data-role='content'] .container"); Prompts this warning: Checks that jQuery selectors are used in an efficient way. It suggests to split descendant selectors which are prefaced with ID selector and warns about duplicated selectors which could be cached. So my question is: Why is this inefficient and what is the efficient way to do the

问题 I have an html ID I'm trying to call. It has a specific name build like this name_|_anyting but when I try to get the elemetn using Jquery's selectors I get an error $("#name_|_anyting") Error: Syntax error, unrecognized expression: |_anyting so my question is : Are pipe characters not allowed as Ids in jquery selectors ? 回答1: | is a special character in selector syntax, which means you can't use it directly in an ID selector. If you cannot change the ID in your markup to accommodate your
