innerHTML adds text but not html tags

阅读更多关于 innerHTML adds text but not html tags

First off sorry for this beginner question but I just recently learned JavaScript and I am now learning to develop Windows 8 apps. Here is the code in question: var numbers = [1, 2, 3, 4, 5]; id('numberList').innerHTML = '<ul>'; for (var x in numbers) { id('numberList').innerHTML += '<li>' + x + '</li>'; } id('numberList').innerHTML = '</ul>'; I have this in the "ready" function (for any Windows 8 developers) in my JS file and 'numbersList' refers to a section tag in the body (of the HTML file). The list does not show up at all when I am running the app. However when I simply try to add text

How to correctly use innerHTML to create an element (with possible children) from a html string?

阅读更多关于 How to correctly use innerHTML to create an element (with possible children) from a html string?

问题 Note: I do NOT want to use any framework. The goal is just to create a function that will return an element based on an HTML string. Assume a simple HTML Document like such: <html> <head></head> <body> </body> </html> All functions mentioned are in included the head section and all DOM creation/manipulation is done at the end of the body in a script tag. I have a function createElement that takes a well formed HTML String as an argument. It goes like this: function createElement(str) { var

javascript change innerhtml

ok im new at javascript, but im trying to change the innerhtml of a div tag, heres my script and its not working: <head> <script type="text/javascript"> function var1() { document.getElementById('test').innerHTML = 'hi'; } window.onLoad = var1(); </script> </head> <body> <div id="test">change</div> </body> it should work but for some reason its not, any help? Aistina Rather than assigning var1 to window.onload , you're currently calling the function and storing its result. Also, this might be obvious, but var1 seems like an odd name for a function. Try this: function var1() { document

Modifying the innerHTML of a <style> element in IE8

阅读更多关于 Modifying the innerHTML of a element in IE8

I am creating a style element and I need to put some CSS into it. The below code works in Chrome, Safari and FF, but fails in IE8: var styleElement = document.createElement("style"); styleElement.type = "text/css"; styleElement.innerHTML = "body{background:red}"; document.head.appendChild(styleElement); In IE8, the code fails when it comes to the innerHTML part. I've tried doing: var inner = document.createTextNode("body{background:red}"); styleElement.appendChild(inner); But this also fails with "Unexpected call to method or property access." I'm looking for a workaround or fix. Use

问题 I need to Hide all <a> elements with text or innerHTML that matches the number 'foo' or a custom value using javascript or jQuery. <li><a href="#" class="dir">foo</a></li> I have tried jQuery(document).ready(function() { if (jquery().text().html("foo"){ ('li >a').fadeOut() } }); 回答1: $('a:contains(foo)').hide(); Done.

AngularJS element.innerHTML is undefined from within directive

阅读更多关于 AngularJS element.innerHTML is undefined from within directive

Let's say I have: directives.directive('foo', function () { return { restrict:'A', scope: true, link:function (scope, element, attr) { console.log('innerHTML is ' + element.innerHTML); scope.$watch('update', function (newValue) { console.log('innerHTML is... ' + element.innerHTML); }); } } }); ... then innerHTML is undefined. I imagine this is due to the way Angular processes the DOM. What is the right way to obtain the innerHTML? The element variable that is passed to your link function is a jqLite object - not a DOM object. You can obtain the DOM object with element[0] (like you could in

TagBuilder InnerHtml in ASP.NET 5 MVC 6

阅读更多关于 TagBuilder InnerHtml in ASP.NET 5 MVC 6

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效，请关闭广告屏蔽插件后再试): 问题: It seems to me that there are major breaking changes in TagBuilder as of beta7 with no mention about them in the announcements repo. Specifically .ToString no longer renders the tagbuilder, it just returns the name of the type. previously we could do things like this inside our HtmlHelper extensions to build up nested html elements: var li = new TagBuilder("li"); li.AddCssClass("inactive"); var span = new TagBuilder("span"); span.SetInnerText(somestring); li.InnerHtml = span.ToString(); .InnerHtml now no longer accepts string because it is
