dom-manipulation

问题 I have a jQuery set of elements that I get from my DOM by calling: $(".some-selector"); All my elements are DIVs each in its own line. My DIVs are set CSS (among other things) display: inline-block; which prevents them from rendering as block elements (each in its own line). The problem is that when these DIV are rendered they have spaces between them because there's line break in the document between each element. I'm comfortable with that. I could of course use float:left that would get rid

问题 Redacted question and example I'm trying to get Knockout components to bind after the initial ko.applyBindings(); so I can add custom elements dynamically. In my original post I referred to loading content by ajax, but my problem occurs when custom elements are added to the DOM using something like jQuery append . Here's an example: $(function() { // Register a simple widget: ko.components.register('like-widget', { template: '<div class="alert alert-info">This is the widget</div>' }); //

问题 I am trying to understand exactly what is updated with the regular DOM after a DOM manipulation. Suppose we have the DOM below and I use javascript to delete the li with the class blue. Does this mean that the browser looks at the parent of class blue (eg: id of list 1) and re-renders that DOM node including all the children (minus class blue) and then repaints the whole page based on any css rules? I would think that would be the process but I wasn't sure and can't find any concrete examples

问题 I am quite new to manipulating elements in the DOM in JS so I am creating a simple to do list to get more comfortable and where I can add items using the input and remove items by clicking on the list item. ALthough this may not be best practice and limitting I am just wanting to use create and remove elements rather than using objects or classes until I get more familar, also using plain/vanilla js so please keep this in mind when answering.

问题 I could just do <my-awesome-component *ngIf="ConditionToIncludeComponent"></my-awesome-component> But every document on inserting component in dom dynamically is based on ViewContainerRef. I like what it does. But what makes it so special over *ngif? Just point out pros and cons of both. Please. Thanks! 回答1: TLDR; If you don't know what component will be used in a component template when putting together this template use viewContainerRef . If you do know the component beforehand but it can

问题 In Javascript I load some elements via AJAX from a server, and for each data-element I create a <div> that contains another div and an <img> . The inner div contains between 2 and 5 lines of text. I arrange three of this items side by side in a row, then the next three in the next row and so on. But since the texts have different lengths, I want to do some fine-adjustment of the elements within each row. I want the top-edges of all three images to be on the same height. To do this, I do this:

问题 I have a angular directive which will produce bootstrap form-group, looks for $scope.errors for value of ng-model of the directive to show errors..

问题 Why doesn't this code work in IE? Please help fix it: jQuery('body').live('DOMNodeInserted',function(e){ var parent = jQuery(e.target).parent(); parent.find("a").css('color','#AA62C6'); parent.find('a').removeAttr('onmousedown'); }); 回答1: This event is not supported in IE. This is added to IE9 but seems to be buggy in the implementation. A solution will be to handle the dom manipulation at the base(The method which is changing the dom) level. function update(){ //do some dom manipulation $
