问题 the following doesn't work , why ? var myWindow=null; myWindow = window.open(targetUrlVar,"_blank","resizable=yes"); $(myWindow).load(function(){ alert('hello'); }); Though MyWindow is a Window reference, no check is performed to see whether or not it has been fully loaded. i thought $(window).load(...) would work here for "window " being replaced by "MyWindow". the following works: $(myWindow).load(function(){ alert('hello'); }); for targetUrlVar being an internal resource (like a page

问题 I have a PHP page with a few iFrames that cause the page to load fairly slowly. How do I go about only loading those iFrames once the page has completely loaded? I assume I need to use JavaScript but I haven't yet found a code that works. Many thanks. EDIT - The iFrame needs to appear within a PHP echo. Here's the code: <?php while($i = mysql_fetch_array($e)) { ?> <div class='dhtmlgoodies_question'> <div style='float:left'><img src='../images/categories/<?=$i[Category]?>.png'></div> <div

问题 I have a Windows Azure VM running VS2013 Load Test Controller and a second Azure VM running 2013 Load Test Agent. I have not been able to get the two communicating successfully. I added the hostname and IP of each VM to the other's HOSTS file. I also created a local admin account with the same username and password on both machines. Neither machine is joined to a domain. I have also created endpoints for each VM to port 6901/TCP. I am able to telnet from the agent VM to port 6901 on the

问题 I use AJAX to display content of page B on page A. How can I make jQuery wait for everything to load (text, images etc.) before the content is displayed? $.ajax({ url:"pageB.html", beforeSend: function() { //show loading animation here } success: function(data) { //hide loading animation here $("body").append(data); } }); I use beforeSend to show a loading animation to the user when the AJAX request is being processed. Now I want to "extend" the waiting time so that the loading animation does

问题 In one of my django projects i am using lots of custom jquery scripts and lots of open source jquery plugins. Now if i load all the jquery scripts in my base template, I will be loading a lot of unused javascript code in the templates which do not require any/some of the jquery files that have been loaded which will affect the page load time of that particular template. So, The current approach i am taking is Load the basic jquery scripts in the base template (ones that are required by each

问题 I'm in the middle of picking tools to load test my Ruby on Rails app. So far I'm trying out - apachebench autobench httperf selenium trample Is there anything else worth looking at? I don't have a ton of hardware, so efficiency is a concern. 回答1: The famous one (at least for me): JMeter The Grinder OpenSTA All support simulating concurrent users, can generate decent load, support distributed testing if required (with distributed agent). JMeter and OpenSTA have a recorder and recorded scripts

问题 I am working on a client proposal and they will need to upgrade their network infrastructure to support hosting an ASP.NET application. Essentially, I need to estimate peak usage for a system with a known quantity of users (currently 250). A simple answer like "you'll need a dedicated T1 line" would probably suffice, but I'd like to have data to back it up. Another question referenced NetLimiter, which looks pretty slick for getting a sense of what's being used. My general thought is that I
