由 徘徊边缘 提交于 2019-12-07 03:52:31
问题 I'm trying to refresh a div from Javascript at each loop and see 1, 2, 3, .... The following code works, but only displays the final result (9998). How is it possible to display all the steps?

Auto-Refresh Div in Jade Template (Node.js/Express)

由 半城伤御伤魂 提交于 2019-12-06 15:13:42
问题 I am using Node.js, Express, Jade, and Redis to develop an app that will display spots from a telnet stream provided by reversebeacon.net, which are cross-referenced against Redis databases of amateur radio club members and if they match are displayed on a table on my app. All this is working wonderfully so far. Unfortunately, I have to refresh the entire page to show new spots on the table. I would like to only refresh the div that contains the table (#activeDiv), instead of setting an

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

由 孤人 提交于 2019-12-06 07:16:47
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 idea for a workaround- have a function that checks if some sort of "signal" has been sent (I'd send it

How can I keep a music player in the page footer that doesn't reload when I click a link to a subpage?

问题 I have been trying to solve this problem for a while now and have looked on numerous forums to find a solution. Here is my setup. Any help would be greatly appreciated! I currently have a index page that loads a JavaScript header and footer above and below my "content" section. I also have a list of navigation links inside of the header. My music player is located in the footer. It does not load automatically (for those that are bothered by that), and i don't want it to reload every time

Javascript code to detect any page changes? (maybe via AJAX)

由 ╄→尐↘猪︶ㄣ 提交于 2019-12-04 15:57:34
问题 Ok so I'm new to writing javascript, and here's what I'm doing/trying to do. When a page loads (window.onload) my javascript code goes through all the forms in a page and attaches a certain "onchange" method to them. This works fine for most websites on the internet, except when a page dynamically updates to load more forms on the page. How do I detect such an event and re-run my function? For example: The Facebook Newsfeed has a bunch of forms associated with all the different statuses/links

Lifehacker implemention of url change with Ajax

由 [亡魂溺海] 提交于 2019-12-03 17:36:42
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 I have. Did I do everything right? <script type="text/javascript"> var httpRequest; var globalurl;
