I have been struggling with a cross browser solution to loading
external javascript files on the fly.
I have been successful using the following code in IE6:
var newScr = document.createElement("SCRIPT");
newScr.src = "newScr.js";
newScr.type="text/javascript";
document.getElementsByTagName("head")[0].appendChild(newScr);
I believe the reason is that IE is loading the external file
syncronously while Firefox is not. Is there an onload event for
creating an element (if so I do not see it in Venkman). I have seen the
solution of using XMLHTTP to load the script but I am trying to get
around any dependency (atleast at this stage of the library) on
activex.
Here's what I'd like to do using pure JavaScript and HTML (no Ajax or PHP): My website loads different JavaScript files dynamically which contain a bunch of data, that I will display on the website. The dynamical loading function is placed in the <HEAD> and looks like that:
Code: function loadJsFile(filename){ console.log("loading js file") var fileref=document.createElement('script') fileref.setAttribute("type","text/javascript") fileref.setAttribute("src", filename) fileref.onload = dataIsLoaded; if (typeof fileref!="undefined"){ document.getElementsByTagName("head")[0].appendChild(fileref) }}
The dataIsLoaded method in there is a callback that is triggered when the JavaScript file has been loaded: Code: function dataIsLoaded(){ console.log("loading js file done") dataLoaded = true; data = new Data(); }
DataLoaded is simply a global boolean that is per default false and the 'data' variable contains all the data I want to display on my site. While the JavaScript file is being loaded, the browser continues building the site. When it gets to the <body> that wants to access some information from the data variable, I get the unsurprising error that 'data' is undefined. I looked for a way to wait until 'data' is defined and then continue with building the <body> but couldn't find a solution.
Alternatively I wanted to reload the divs in the <body> when the 'data' is available: Code: function reloadDivs(){ if(dataLoaded){ console.log("data available, reloading divs"); document.getElementById('someDiv').innerHTML = document.getElementById('someDiv').innerHTML }else{ console.log("data is not yet available"); setTimeout('loadReportData();', 500); }} This does not work, I get a blank div when I do that.
4. In Firefox, it works beautifully ( no shock ) 5. In IE it does not ( no shock ) 6. If i put the function in inline <scripttags in my HTML, the JS runs fine (no syntax error).
I need a way of loading api scripts on the fly. ie. if the user clicks on a link the javascript would suck in the api script depending on what the user has selected. By api script I mean:
I am using the maps24 api to build an address finder - ie. put your postcode/zipcode in and populate the rest of the address details. For some reason you need to load a different js file for each region (north america, europe, etc). I want my users to click on their region and have the <script> tags inserted into the head. I have done this using javascript but the functions don't seem to be available. I am assuming that the page needs to refresh??
Does anyone know away of making the javascript functions available to use without having to refresh the page? In other words, loading javascript files on the fly.
I have a problem of client side XSL transformation. I sent the XML and the XSL to the client in XML data islands. Using the transform Node method the HTML is returned. There is however some script tag in the XSL file which references external ..js files they are like
Now, after transformation the function from this .js file are not called and object required errors are thrown. This is despite the fact that IE has downloaded the .js file and they are visisble in the cache (Temporary Internet Files). This problem only occurs if the .js file is not present in the cache, hence it happens when the user visits some site for the first time.
I came up with some code to load javascript files dynamically. But I've got problems..
When the script element is dynamically added to the head section of html, i think that the document.ready event fires once again and therefore the code sort of runs twice.
In the html page I call this method:
In the script test.js I have the function SayHi():
The SayHi method never gets called and alert('begin') & alert('getScript') get called twice in this sequence:begin begin getScript getScript.
I am working on a client's site and he has some external javascript code that his affiliates can put on their websites to fetch some data. However, when my client's site goes down, the affiliates' sites cease to load thus taking their sites down with it.
Is there any way I can have the javascript check to see if the website is up before loading, and if it is, run this: Code:
I have the following JavaScript (see below). The script requests an XML file from the server and displays it on the page.The script works fine when the requested XML file is stored on the same server as the script.The problem is when I try requesting an XML file from an external server such as the National Weather Service. I get an error. If I take the XML file from the National Weather Service and save it to my server it works. Why can't I use my script to request XML files stored on external servers?
Javascript Code
Code:
window.onload = initAll; var xhr = false; function initAll() { document.getElementById("makeTextRequest").onclick = getNewFile;
I've tried looking at various online sources but they are all either too technical or don't seem to work. I'm obviously doing something wrong!The code is posted below, it's not very long so hopefully someone will be able to debug it!Original page:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head>
function alertfunc() { sometext = window.frames['alertiframe'].document.all.tags['to'][0].innerHTML; alert(sometext); }
</script>
<a href="javascript:alertfunc()">Click Me</a>
I am working with an older browser more of MAC IE. It works with DOM 1 and extremely partially with DOM 2. contentDocument and contentWindow does not work on this browser.
The above code works very nicely, however as soon as I rename the file to "xmlsample.xml" with an xml extension, it does not work anywork. If you have any other solutions please let me know. Rem we can't use any newer techniques, this is very basic DOM.
I have a question related to calling external JS files.
I have the following code in a .JS file:
document.writeln('<a href="http://www.xyz.com" TARGET="_BLANK" TITLE="For an online directory of distance graduate programs, click here!"> Click here!</a>');
It works perfectly...
I would like to add a mouseover command to it, i.e.: onMouseOver="window.status='Click here now to visit Education.com!'return true" OnMouseOut="window.status=''return true"
I've used the correct slashes in the right places. However, it doesn't work; probably because I'm trying to place Javascript within Javascript. How can I place the onMouseOver command in the code at the top of this page?
I am working on JS navigation for my web page. Contents of 3 subpages are located in the array as shown below. When certain key is pressed on the page, div is filled with data taken from one of the array rows.
*** var content=new Array() content[1]='<p>some text</p>' content[2]='<p>some other text</p>' content[3]='<p>yet another text</p>' ***
The question is: is it possible in some simple way to put the data from those 3 rows into 3 separate files and make the JS code to take the data from those files? (I want to have 3 files with plain HTML) If so, please show me some example how to do that. Or give me some address where I can read about it, please. I have been using Google for several hours - unfortunately without any luck.
In general - here is what I would like to do:
*** var content=new Array() content[1]=[contents of Ƈ.html' file] content[2]=[contents of ƈ.html' file] content[3]=[contents of Ɖ.html' file] ***
I have a dynamic (PHP) external JavaScript file. I need to load that file every X seconds and execute its contents, given the the page is already 'Done' (fully downloaded).
So right now I'm able to execute javascript code on my website without the use of <script> tags. Example: <body onload=alert("cool");></body>
What I want to be able to do is insert an external javascript file located at another website using JavaScript code (not script tags). How can this be done?
I built a small JavaScript file that does some HTML and CSS manipulation when you hover over any tag with a certain class. It works great when running on the same server, but if I try to use the JS as an external script, the hover event isn't triggering. Here is my external JS file code:
$(document).ready(function() { alert('i work inside'); $(".start").hover( function (e) {
I am using a 3 column layout. One column contains links and 2 columns contain content. I need to load the content to 2 Divs in one click. When a link is clicked it should load some file in column 2 and another file in column 3.
As of now I am loading only one div using jquery load function. But I need to load 2 divs. Below is the code Ib am using.
Or is there any other option to load 2 external files in 2 different div in one click
Example
Head <script type="text/javascript"> $(document).ready(function(){ $('a.menu_links
I am implementing Ajax for a new website and I've run into a hurdle.
It seems like Javascript does not 'see' any div elements that are loaded from external file with Ajax.
Is this a common issue, and is there a solution? Or am I overlooking something obvious?
What I'm doing is loading a simple external page via Ajax. The pages loads just fine, and it contains div's with unique id's. If I execute a Javascript function, it seems to not recognize these newly-rendered div's from the Ajax external file. Is this the case? Can Javascript be re-invoked on command, so it can see the new div's?
I'm using the asynchronous example from [URL] to load a backup jQuery CDN if the main Google fails or goes undefined for some reason. The default script loads the backup (ASPNET CDN) but if I want to add a local copy backup to the ASPNET CDN, it will not load if the ASPNET CDN is down. I tried different variations with no success. Here is the code:
Code JavaScript: // Setup backups var jqbackup1 = '//ajax.aspnetcdn.com/ajax/jQuery/jquery-1.4.4.min.js'; var jqbackup2 = '/js/jquery-1.4.4.min.js'; // Setup getScript function function getScript(url, success) { [Code]...
View source code of external files in html like *.js and *.css For example: In this page I am Posting to, there are 24 *.js files. They are loaded but you can't see them. I would like to view some of these external javascript files for study. Not necessarily on this site, but where ever I find them.
