innerhtml

问题 I've got a large piece of text which I want to be able to select, storing the selected part by its startindex and endindex . (For example, selecting or in word would give me startindex 1 and endindex 2 .) This all works properly, but I've got a problem with HTML entities such as & (the ampersand). I've created a little case in which the issue consists. You can see in the fiddle below that the startIndex inflates if you select anything beyond the & , because it doesn't count the & as a single

问题 I'm trying to build a dynamic table in javascript with innerHTML. When the web app runs, it only prints the console.log, but doesn't build a table. I tried two ways: First: success: function (data, status, jqXHR) { $.each(data, function (index, dati) { console.log(dati) var html = "<table width=\'450\' bgcolor=\'white\' border=\'2\' bordercolor=\'black\' cellpadding=\'10\' cellspacing=\'1\'>\n" + " <tr style=min-width:850px>\n" + " <td>dati.codiceCOmmessa </td>\n" + " <td>dati.commessaMainSub

问题 I'm trying to load WebBrowser content and after that I want to add some text and scroll to the bottom. Here's example of my code: webBrowser1.Url = new System.Uri("file:///" + filePath); webBrowser1.Document.Body.InnerHtml += text; webBrowser1.Document.Body.ScrollTop = webBrowser1.Document.Body.ScrollRectangle.Height; When I run it, there's an unhandled exception "Object reference not set to an instance of an object". Or when I comment line that does the scrolling, then text is added to

问题 So, I wrote a script that loads images one at a time in a new tab... Got a stop button to work thanks to Brock over HERE... Then I broke it adding in the counter that I had written in while waiting for an answer to that question. I can't see any reason that should have broke it... help please? My Script: var box = document.createElement ('div'); box.id = 'mySelectBox'; GM_addStyle ( ' #mySelectBox { ' + ' background: white; ' + ' border: 2px solid red; ' + ' padding: 4px; ' + //' position:

问题 I'm trying to add a button to the webpage, from the code behind. I have a single empty div on my main page that visible on and off, when needed. However the content I wish to create dynamically as the div content can change dependent on conditions. I have realised that within my ASP Control I use a / (backslash) which cancels out my HTML. The problem I now have is understanding how I can get around this with code, is there a way to add ASP Controls to the web page? I am open to suggestions

问题 OK, this is an embarrassingly simple question. Why doesn't the following jQuery example work? Obviously it is supposed to change the 'a' in the table to 'hello'. HTML code: <table id='table1'> <tr> <td>a</td> <td>b</td> </tr> </table>​ JavaScript (JQuery) code: $("#table1 td:contains('a')").innerHTML="hello"; 回答1: use the html function like this $("#table1 td:contains('a')").html("hallo"); if you want use innerHTML (is a DOM method, not a Jquery Method), you have to select the DOMElement

问题 Why is this breaking? I've not used .innerHTML correctly before and don't know why this would be wrong. function asdf() { document.getElementById("qwerty").innerHTML="A<br> B<br> C<br> D<br>"; } 回答1: You have to escape new-lines in JavaScript string-literals: function asdf() { document.getElementById("qwerty").innerHTML="A<br>\ B<br>\ C<br>\ D<br>"; } Though you could, potentially more-easily, simply insert newlines in the string itself: function asdf() { document.getElementById("qwerty")

问题 I always thought that jQuery operates only on DOM elements , that is those nodes that have nodeType == 1 . However I'm shocked that while creating HTML $("<p> </p><!-- comment -->") results in: [p, Comment { data=" comment ", length=21, nodeName="#comment", more...}] (Firebug formatting) I accepted some HTML by AJAX and a DOM Comment was created this way and passed somewhere to a function that is applicable only to elements: defaultView.getComputedStyle( elem, null ) Is there some clean way
