JavaScript - Unable To Get The Document Object For The Main Page Of Certain Sites In Opera
We are building an opera extension in which we are trying to use the document object property (document.body.innerHTML) in order to obtain the source of the main page of a site. In most cases it provides us with the correct page source but for certain sites (ones that have multiple document layers), it doesn't return the top most document.
For instance, for the site (https://www.pcisecuritystandards.org/) we would like to source for the main page that is displayed but once the entire page is loaded, the document property would display the source for another layer (https://s7.addthis.com/static/r07/sh...rev=86981&xd=1) This perhaps has to do with how opera loads the document layers in a page. We did not face any issue with any other browser How can we obtain the source of the main page (https://www.pcisecuritystandards.org/) using the document object in Opera ?

How could the movingword be null when I have declared it in my code? The following is my code: Code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"

I read tutorials and pdfs on the DOM and its pissing me off coz ther not showing me or answering my questions. Can someone please explain to me how to use the DOM. Like: 1) Can i create child nodes or parents? And if so when and how? 2) How do i look at a parent node (lets say of a list) and select a specific child (part of the list)? Thank You Ok guys, i am starting from he http://www.javascriptkit.com/javatutors/primer5.shtml Code: <script type="text/javascript">
var example
example=document.lastModified
document.write("This page was last modified: "+example)
</script>
I am having trouble understanding an actual situation which may require the above coding, can anyone give an example please? IE is throwing an error stating window.document.forms[...].elements is null or not an object. in the following code Code: var changeHandler = function() {
this.form.calculateDependencies();
return true;
};
for(var i = 0; i < arguments.length; ++i) {
for(var j = 0, e = window.document.forms[arguments[i]].elements; j < e.length; ++j) {
addEvents([e[j]], ["change", "keyup", "focus", "click", "keydown"], changeHandler);
e[j].hide = hideEl;
e[j].show = showEl;
}
(e = window.document.forms[arguments[i]]).calculateDependencies = calcDeps;
e.calculateDependencies();
}
}
FF and Chrome seem to work ok, but it breaks in IE. What am I doing wrong here? Hi, first post here. I was working on code for opening a link in a new window when clicked. I read somewhere that it's a good idea to remove all of the javascript elements from the HTML. So I pieced it together and it works. But I get the following error in IE8: Code: Message: 'document.getElementById(...)' is null or not an object Here's the relevant HTML: Code: <a href="http://www.samplesite.com" id="sampleid">Sample Text</a> And here's the relevant javascript that I put in a seperate .js file: Code: function samplefct() {
window.open(this.href);return false;
}
window.onload = function()
{document.getElementById("sampleid").onclick = samplefct;
}
The code does work as planned. But I'd still like to get rid of the error. Can anybody think of a different way of stating the javascript that would perform the same thing and lose the error? Any help would be greatly appreciated. Thanks! IB I have a web site application written in VB.net and asp. The main page uses JavaScript to load a popup page that performs multiple tasks. The main page accepts a variety of incoming messages, only SOME of which need to be passed to this popup page for processing. I found an ugly way to pass the message to the popup by placing it in a Session variable. Now I need to cause it to be handled. I see two possibilities, and I do not have a clue how to implement either. Either one would be great: 1. In the main page, trigger a subroutine in the popup, using JavaScript. OR 2. In the popup, establish a trigger any time that Session variable changes. Hello, glad to be here!! So I am curious about a simple script to play a main video, with thumbnails below. What I am wanting is when you click on a thumb, it plays in the main video spot. Hope this isn't much, but donations are allowed if it is. hi i have a html page that has a link "OPEN POP UP" when this link is clicked a new pop up window is opened. and this pop has two LINKS first is ONE and second is TWO. what i want to do is. when any of these LINKS is clicked on the popup the should close and the my main html page from where the popup came should execute a javascript function. please help Hello, I had a php page, which contains links when I click on a link it will issue a new page, I want to make the main page to be refreshed once the new page being closed. Any suggestions? thanks Folks I'm using the code below to create a pop-up search box that finds text strings on a contents page. The contents page contains a list of hyperlinks each of which opens a PDF document in the same window. The search box does exactly what it's intended to do, but the problem is this: if the user clicks on "Find next" or "Find previous" once the PDF document is open, an error occurs; the same error occurs if the user then navigates back to the contents page and clicks on "Find next" or "Find previous". I'm thinking the solution must be to get the search box to close as soon as the PDF document opens, but how do I achieve this? Thanks Remster Code: <html>

First, I will state that I am totally inexperienced in JavaScript. I have a web site application written in VB.net and asp. The main page uses JavaScript to load a popup page that performs multiple tasks. The main page accepts a variety of incoming messages, only SOME of which need to be passed to this popup page for processing. I found an ugly way to pass the message to the popup by placing it in a Session variable. Now I need to cause it to be handled.

Thanks in advance for any help on this. how i can refresh my main history page without page refresh alert message? i am using the following code on the submitpage.asp <%response.write ("<script>window.location.reload(history.go(-2));</script>")%> i got the attached message when it refreshes the main page. is there is a way to refresh directly without this message? Hi, I am not able to submit the page details in IE 6 since am getting Javascript error: "unknown name" while submitting the page. If i press submit button for second time getting javascript error "Permission Denied". I tried to submit the details in IE 7 aswell the same error occurs. But i tried to submit the page in FireFox, its worked great... submitted without any error and the details saved in the database. I dont understand why the details are not submitted through IE6. Please assist on this. rgds, Ganny. I'm using a nice little script which replaces the usual file upload input with whatever image you want and then with JS makes sure that an invisible 'browse' button is underneath the mouse pointer whenever the mouse is moved over the image you want to use. Nice It works on every browser ie7 ie8 ie9 FF safari chrome but not on opera. On Opera the regular file input appears. I've had a good hoke round the 'net and I know there's loads of scripts which do similar things. But either they are too complicated for me to figure out how to use them eg uploadify (bit of a newbie) or they do similar things but just not as well - like making the custom image the same size as the file input would be (there's issues with that too). here's the script I'm using - there's not much to it How come it doesn't work in Opera grrrr... Is there anyway to fix it? This is perfect for what I want apart from not working in Opera So I have an HTML page with javascript that takes input values, computes some results, and then puts these results in a table. Works great. Now I realize some users might want to print just the results table. So I add a button that allows the user to request the table in a separate window; clicking the button invokes a script to re-create the table in a separate window. Works fine except: * In the status bar, the window appears to never finish loading * If you go to File -> Print then nothing seems to happen; however, if you close the generated window _then_ the print dialog appears; the window you want to print, however, is gone. Any suggestions? The code invoked by clicking the newly added button: [CODE] function grabResults() { var w = window.open("","ROIResults"+winCount++, "height=400,width=600,menubar=yes"); var d = w.document; d.write('<head>'); d.write('<link href="style.css" title="compact" rel="stylesheet" type="text/css" />'); d.write('<title>Return On Investment Calculations</title>'); d.write('</head>'); d.write('<body>'); d.write('<div id="logoholder">'); d.write(' <img src="TTFlogo2.gif" alt="Cannott display logo" "width="322" width="322" height="51"></p>'); d.write('</div>'); d.write('<div id="header">'); d.write(' <h2>Return on Investment Estimator for Classroom Training</h2>'); d.write('</div>'); d.write('<table rules="all" frame="box">'); d.write('<caption>Results - Estimated ROI</caption>'); d.write(' <tr><th>Course</th>'); d.write('<td class="center" id="courseName">'+cname+'</td>'); d.write(' </tr>'); d.write(' <tr><th>Duration (Days)</th>'); d.write('<td class="center" id="courseDur">'+cdays+'</td>'); d.write(' </tr>'); d.write(' <tr><th>Class Size</th>'); d.write('<td class="center" id="courseSize">'+csize+'</td>'); d.write(' </tr>'); d.write(' <tr><th>Location</th>'); d.write('<td class="center" id="courseLoc">'+teach_loc+'</td>'); d.write(' </tr>'); d.write(' <tr><th>Training Cost</th>'); d.write('<td class="justr" id="courseCost">'+TC+'</td>'); d.write(' </tr>'); d.write(' <tr><th>Initial Value</th>'); d.write('<td class="justr" id="courseInitial">'+startValue+'</td>'); d.write(' </tr>'); d.write(' <tr><th>Returned Value</th>'); d.write('<td class="justr" id="courseValue">'+RV+'</td>'); d.write(' </tr>'); d.write(' <tr><th>Increase in Value</th>'); d.write('<td class="justr" id="courseIncr">'+Inc+'</td>'); d.write(' </tr>'); d.write(' <tr><th>Net ROI after costs</th>'); d.write('<td class="justr" id="courseROI">'+ROI+'</td>'); d.write(' </tr>'); d.write(' <tr><th>ROI Rate</th>'); d.write('<td class="justr" id="courseROIRate">'+ROIR.toFixed(2)+'%</td>'); d.write('</tr> '); */ d.write('</table>'); d.write('<p class="in3">(All amounts are in US Dollars.)</p>'); d.write('</body>'); d.write('</html>'); d.close(); return true; } [ICODE] I've written the following html, <html> <head> <script type="text/javascript"> function createpage(){ var first = document.getElementById('first').value var second = document.getElementById('second').value var third = document.getElementById('third').value var j = window.open('random'); var new_page = '<html><head><script type="text/javascript">function open_win() { window.open(first) window.open(second) window.open(third) } </script></head><body onLoad = "open_win()"></body></html>'; j.document.write(new_page); j.document.close(); } </script> </head> <body> <form action=""> <p> First Link: <input type="text" id="first" name="first"/> Second Link: <input type="text" id="second" name="second"/> Third Link: <input type="text" id="third" name="third"/> <input type=BUTTON value="Submit" name="mySubmit" onClick="createpage();return false;"> </p> </form> </body> </html> With the intention to eventually implement it into a website that "mashes" several URLs together into a tinyurl that, upon being opened, creates several tabs of the content the creator wanted in the single URL. Does that make sense? In order to best do this I figured a page with a random character string (I haven't yet implemented this part, for now 'random' holds the place of the new page/link) would have to be created that would launch all the tabs and then close itself. Here's what it should do... 1) User enter 3 URLs into three forms: First Link: <input type="text" id="first" name="first"/> Second Link: <input type="text" id="second" name="second"/> Third Link: <input type="text" id="third" name="third"/> 2) User clicks Submit button that calls "createpage()" function that's declared in the <head>er. The first part of this function declares the links that were inputted as variables first, second, and, third. <script type="text/javascript"> function createpage(){ var first = document.getElementById('first').value var second = document.getElementById('second').value var third = document.getElementById('third').value 3) "createpage()" function then declares a new window named 'random' to variable j (I have random.html stored in the same folder as this project. It is empty.) var j = window.open('random') 4) Next "createpage()" creates a variable that stores a full page's html code that includes a script that launches each link individually with window.open(). var new_page = '<html><head><script type="text/javascript">function open_win() { window.open(first) window.open(second) window.open(third) } </script></head><body onLoad = "open_win()"></body></html>'; 5) "createpage()" writes the code (stored in variable 'new_page') to document 'random' with j.document.write(new_page); 6) "createpage()" closes the document. Hi. I have a question about java script code. I'm creating a website with frames. Within the main page frame, there are tables in the main content page. When I created the website, it fit perfectly in the browser window of my smaller laptop. I just checked it out on my old G5 and the images/pages are too big and either cut off or scroll bars appear (which is not what I want) So I wanted to know what code I put in my files and where to put it? Also, what pages does it need to be in? the main frame index page? the specific pages that fit within the frames? some are images that load in the frames? would i need to create an .html for those and then have the .jpg load so that it can be resized? I need the main page to be resized to fit the browser as well as the pages in the frames to fit. Can you help? Thanks Probably a stupid noob question, is there any way I can stop document.write from outputting info to a new page I would prefer to have it shown in a textarea. Info from an array that is suppose to display in a text area when button is clicked and when another button is clicked it is suppose to show some other info. But what happens is the first info displays in textarea for a few seconds and then the second info is displayed but on a new page and not the textarea where I want it to go I have marked code within the code // I want this specific code to be displayed second but I know its in the wrong spot. Here is the code [CODE] function show() { var myArray = new Array(); myArray[0] = document.getElementById('fullname').value; ' myArray[1] = document.getElementById('address').value; myArray[2] = document.getElementById('phone').value; myArray[3] = document.getElementById('email').value; //Code I want to display second in the textarea //var string = myArray.join("\n") //document.getElementById('textarea').value = string; document.writeln('Thank you for registering,' + ' ' + myArray[0] + '. Your membership will be confirmed by E-mail to ' + myArray[2] + "<br>"); document.writeln('Registration Details:') document.writeln("<br>") for (var i=0; i<myArray.length; i++) { document.write(myArray[i] + "<br>"); } } [\CODE] Thanks in advance |
