问题 I'm working on a music site: I have a text file on the server which contains the name of the currently playing song. I would like read the text file every fifteeen seconds, and change the text displayed on my site, without a refresh. Now, using a little jQuery and javascript, I have actually gotten to the point where the file is read and displayed the first time, but it wont refresh . I have attempted all sorts of setInterval functions, but for the life of me I cant get this part to work. Any

Lifehacker implemention of url change with Ajax

问题 I see that Lifehacker is able to change the url while using AJAX to update part of the page. I guess that can be implemented using HTML5 or history.js plugin, but I guess lifehacker is using neither. Does any one has a clue on how they do it? I am new to AJAX and just managed to update part of the page using Ajax. Thank you @Robin Anderson for a detailed step by step algo. I tried it and it is working fine. However, before I can test it on production, I would like to run by you the code that

问题 I may be reinventing the wheel but that's intentional. I am trying to make a real-time chat application using PHP HTML MySQL CSS. It's working quite well over the network and grabbing new content every second. In IE you can notice a flicker every second, seemingly it is pulling all that data again and again, even if there's no new content, and I don't like that. Here is my refresh JS code: $(document).ready(function() { $("#data").load("data.php"); var refreshId = setInterval(function() { $("

Check for newer version of page, and if existing, reload

由 笑着哭i 提交于 2019-12-12 10:06:50
问题 Basically, I want my page (say page.html) to check if a newer version of page.html exists, and if so, refresh the page, and in doing so, bring up the newer version. I realize this happens automatically after some time- however, I want this to happen within the time of 30 seconds to 2 minutes. I'm not sure how this would be accomplished- perhaps some Javascript? if(/*newer version exists*/) { location.reload(); } The part I'm unsure about is how to detect if a newer version exists. I had an

Is it possible to create a variable, that doesn't change on refresh the page, in javascript?

由 给你一囗甜甜゛ 提交于 2019-12-11 01:38:40
问题 After I ask this question: I was thinking about this solution: Create a boolean flag inside the javascript script and make it true : true indicates refreshing the page using the browser. false indicates refreshing the page using a button. Inside onclick attribute of the button, I set flag to false and call window.location.reload() to refresh the page. Inside onload attribute of <body> tag, I check the flag if it's true switch to Home tab else switch to Page1 tab where it contains the <div>

Refreshing Partial View in MVC 3

由 末鹿安然 提交于 2019-12-08 06:35:43
问题 I have a partial view that I have included on my _Layout.cshtml. It simply has a javascript function that changes an image based on the state of my system. I don't need to reload any data, I don't need to go to the code of the controller for anything, I simply need to reload that partial view. I tried many of the examples that I found here but couldn't get any of them to work. I felt as if they were too complex for what I was doing anyway. Any guidance would be appreciated.
