The question is about this article: https://www.html5rocks.com/en/tutorials/speed/script-loading/ They are saying this: <script src="//other-domain.com/1.js"></script> <script src="2.js"></script> Ahh, blissful simplicity. Here the browser will download both scripts in parallel and execute them as soon as possible, maintaining their order. “2.js” won’t execute until “1.js” has executed (or failed to do so), “1.js” won’t execute until the previous script or stylesheet has executed, etc etc. Unfortunately, the browser blocks further rendering of the page while all this is happening. This is due

Safari and Chrome doesn't evaluate dynamically added <script> tag at page load

阅读更多关于 Safari and Chrome doesn't evaluate dynamically added tag at page load

I am writing small JavaScript code which will load external js files at html page loading. I tested 2 ways. Case 1: Used document.write to add <script> tag. It worked for all browsers (IE, FF, Safari, Chrome, Opera). Case 2: Used DOMElement.appendChild to add <script> tag to the <haed> element. Only worked for IE, FF, and Opera. Did NOT work for Safari and Chrome. In both cases, I expected new <script> tag is being inserted before <head> closing tag. So the new <script> tag is evaluated before processing <body>, and by the time window.onload is called, "success" variable should be true. But it

This code does not work: <div class="pix"><div id="addTimestamp"></div></div> <script type="text/javascript"> (function () { var date = new Date(), timestamp = date.getTime(), newScript = document.createElement("script"); newScript.type = 'text/javascript'; newScript.src = 'someUrl=' + timestamp + '?'; document.getElementById('addTimestamp').appendChild(newScript); }()) </script> The dynamic script adds document.write(someCode which loads banners) . But in Firebug I have an error: Invoking document.write() from asynchronously-loaded external script was ignored. Add this: newScript.async =

How can I create JS event listeners that survive a document.write?

阅读更多关于 How can I create JS event listeners that survive a document.write?

I'm attaching an event listener to the window object. Then later in the script, document.write is being used. (I know, it's evil. I have no choice in the matter.) The problem is, the document.write wipes out my listeners. Is is possible to avoid that? Here's a fiddle that illustrates the problem: http://jsfiddle.net/Fuhzu/ That is not possible. document.write unloads the current document, and creates a new one. A demo to confirm: http://jsfiddle.net/Gk3cX/ window.test = document; //Cache document document.write('<button onclick="alert(window.test===document)">CLick</button>'); // Clicking

How to load third-party javascript tag asynchronously which has document.write

阅读更多关于 How to load third-party javascript tag asynchronously which has document.write

We give out a piece of javascript tags such as <script src="http://ours.com/some.js"></script> which site owners put on their site like http://example.com and in this javascript tag we want to dynamically include a third-party js such as which can have document.write in it, but of course if we try to include it by conventional method, var script_tag = document.createElement('script'); script_tag.type = 'text/javascript'; script_tag.src="http://third-party.com/some.js"; document.getElementById('target').appendChild(script_tag); we get a warning from browser, Warning: A call to document.write()

问题 I work for a company that writes software which client sites embed with < script language="JavaScript" src=..... etc. etc. We depend quite a bit on document.write to write elements out to the page. One of our clients for some reason has opted to use the content-type "application/xhtml+xml", which makes document.write() unusable in chrome. I understand why this is, and that DOM-compliant code should create each element, set its attributes, fill it with a text node if needed, attach the text

Why use document.write?

I was wondering why ad's still use the document.write approach to inserting the add into the page <script language="javascript" type="text/javascript"> document.write("<script type='text/javascript' src='http://addomain/someadd.js'><\/sc" + "ript>"); </script> Why is it that I can't just put <script type='text/javascript' src='http://addomain/someadd.js'></script> In place of the ad? A traditional script tag will block the page while it is loading and executing. A script loaded with document.write will work asynchronously. That's why you see this on ads or analytics, as such scripts don't
