JavaScript - Document.write("goodbye!"); Stops Working When Placed Inside A Function?
ok so
Code: document.write("Goodbye!");
works but I put ^ that inside a function Code: function SayHello ()
(
document.write("Goodbye!");
)
and it stops working? I know the function call works because when I place some code to display an image in SayHello function, it displays the image. Similar TutorialsHi, the following does not work in firefox, note that I have removed the < at the beggining of the script in order to see what was being written, what I am trying to acheive is to write the following to an IFRAME using JavaScript, on click of a button: PHP Code: <script language=javascript type="text/javascript" runat=server> var fso = new ActiveXObject("Scripting.FileSystemObject"); var f = fso.OpenTextFile("somefile.txt", 2, true); f.WriteLine('lblTitle="Color Setup"'); f.WriteLine('scmdSave="Save"'); f.Close();</Script> in order to get this, I wrote a script that goes like this: PHP Code: var frTraductionID = document.getElementById("frTraduction"); frTraductionID = (frTraductionID.contentWindow) ? frTraductionID.contentWindow : (frTraductionID.contentDocument.document) ? frTraductionID.contentDocument.document : frTraductionID.contentDocument; var x=frTraductionID.document.getElementById("hCount").value; var ifrm = document.getElementById("ifUPDATE"); ifrm = (ifrm.contentWindow) ? ifrm.contentWindow : (ifrm.contentDocument.document) ? ifrm.contentDocument.document : ifrm.contentDocument; ifrm.document.open(); ifrm.document.write('scr' + 'ipt language=javascript type="text/javascript" runat=server>'); ifrm.document.write('var fso = new Active' + 'XObject("Scripting.FileSystemObject"); '); ifrm.document.write('var f = fso.OpenTextFile("' + sFileName + '", 2, true); '); for (var i=0;i<x;i+=1) { var sString=""; sString +="f.WriteLine('"; sString +=frTraductionID.document.getElementById("h"+i).value; sString +='="'; sDetail=frTraductionID.document.getElementById("d"+i).value.replace('"', ' '); sDetail=sDetail.replace("'", "`"); sString +=sDetail; sString +='"'; sString +="')"; sString +="; "; alert("i = " + i + " str = " + sString); ifrm.document.write(sString); } ifrm.document.write("f.Close();"); ifrm.document.write("<"); ifrm.document.write("Scr"); ifrm.document.write("ipt>"); ifrm.document.close(); document.getElementById('ifUPDATE').contentWindow.location.reload(true); The problem is that the "<" seam to cause problem, I have intentionally removed the first < in order to see what the result was and here is what I get: PHP Code: script language=javascript type="text/javascript" runat=server>var fso = new ActiveXObject("Scripting.FileSystemObject"); var f = fso.OpenTextFile("//ADMNPC88/VIP/Language/TEST5/COLOR_SETUP.INC", 2, true); f.WriteLine('lblTitle="Color Setup"'); f.WriteLine('scmdSave="Save"'); f.WriteLine('scmdRestore="Restore"'); f.WriteLine('lblControlHeader="Control`s Header"'); f.WriteLine('lblControlDetail="Control`s Detail"'); f.WriteLine('lblControlDetailHL="Control`s Detail Highlighted"'); f.WriteLine('lblLettering="Lettering"'); f.WriteLine('lblHelp="Drag and drop the desired color on the part of the screen for which you want to change the color."'); f.Close(); Note that I am missing the whole tail end </Script> Please help as I cannot figure it out.

Hi guys, i m novice to javascript, i have a piece of code to preview the image after selecting it from file upload control,its working fine in Firefox,but its not working in IE,Chorome,what is the error please let me know,here is my code. function setImage(file) { if (document.all) document.getElementById("<%=prevImage.ClientID %>").src = file.value; else document.getElementById("<%=prevImage.ClientID %>").src = file.files.item(0).getAsDataURL(); if (document.getElementById("<%=prevImage.ClientID %>").src.length > 0) document.getElementById("<%=prevImage.ClientID %>").style.display = 'block'; } . SOURCE: Here Code: 1 document.onmousemove = mouseMove;
2
3 function mouseMove(ev){
4 ev = ev || window.event;
5 var mousePos = mouseCoords(ev);
6 }
7
8 function mouseCoords(ev){
9 if(ev.pageX || ev.pageY){
10 return {x:ev.pageX, y:ev.pageY};
11 }
12 return {
13 x:ev.clientX + document.body.scrollLeft - document.body.clientLeft,
14 y:ev.clientY + document.body.scrollTop - document.body.clientTop
15 };
16 }
#1: How is it that "mouseMove" is assigned to "document.onmousemove" from right-to-left? What exactly is taking place here? #3: How can "mouseMove" be declared as a function afterwards? #3: I periodically see "e" being placed in functions. Is "ev" taking the place for "e"? If so is "ev" or "e" a global object? Where do they initially come from and how do they work? . i have an onclick function, but after debuging i found that firefox and only firefox blocks at the line " individualNames = names.childNodes[0].innerText; " is there somthin im missing please help. function searchForm() { var change = 0; var searchValue = document.getElementById("searchValue").value.toLowerCase(); var count = document.getElementById("excelTable").rows.length; var once = true; myArray = new Array(); if(searchValue == ""){alert("Please enter a value"); return false} for(i=0;i<=count;i++){ names = document.getElementById("excelTable").rows[i]; individualNames = names.childNodes[0].innerText; //only by last name of the file coming in format == "LastName, FirstName" lastName = individualNames.split(", "); //only by last name lowerCaseNames = lastName[0].toLowerCase(); names.style.backgroundColor = "#FFF"; if(lowerCaseNames.indexOf(searchValue) != -1) { names.style.backgroundColor = "#999"; //make the first result with the search apear on screen than stop after the first if(once==true){document.getElementById("excelTable").rows[i].scrollIntoView(true); once=false;} myArray[change] = document.getElementById("excelTable").rows[i];//fill a passing array to next function change++;//make the array go to next slot document.getElementById("nextButton").disabled = false; document.getElementById("searchTitle").scrollIntoView(true); } } } Can someone explain what this does?

Thanks for any response. I'm getting the following problem. The reason is that the object appears through AJAX. But if I choose it NOT to appear it gives this problem. How can I avoid this? I put an if statement inline Code: if(document.getElementById('vsbtitle_1').value!=null){

write on a button command. What can I use insted of document.write? Is it possible to write a 'web site promotion program" - for example, the program will search those PCs using google, and once the users type particular search words, the program will open my web site on that particular PC. I'm working on a website that will basically embed a widget/frame sent by a handler into a user's current page. The user basically adds a script tag to where they would like the HTML to be. The script tag has their settings and is basically a document.write that calls all the code that we want displayed. So here's my problem. We have a map that we need to add in a specific section, and to get the map we have to call another script tag. So we end up having a script tag (map) embedded in another script tag (the code for the widget/frame) or we end up having to document.write inside a document.write. Now this works just fine and as expected in Firefox, Safari, and Chrome. However, Internet Explorer and Opera wait until the first document.write is completely finished before calling the embedded one. Of course the problem with this, is that it takes the map out of the document's flow and just appends it to the bottom left of the page. Since the rest of the page has already been called, there's no way to move the interior "map" script. Any ideas? Basically just trying to figure out how (if even possible) to render an embedded script tag in Internet Explorer and be able to place it properly. I've tried everything that I can think of, including AJAX and Google's unescape script. Any suggestions, I'd greatly appreciate it. Or even if you've encountered a similar problem, and know that it just isn't possible in IE or Opera, that would be fine too. Thanks in advance! hi all, I am fairly new to Javascript, and am trying to "print" a var inside a script. I have this piece of script, which loads images from a gallery: Code: $(document).ready(function(){
$('title').text('G3 Ajax Gallery');
loadGallery('/gallery3/rss/feed/gallery/album/114');
});
The number 114 defines what part of the gallery to be loaded. I would like to define this with a var, but dont know how to "print" it into the url. So: loadGallery('/gallery3/rss/feed/gallery/album/114'); woulkd become something like: loadGallery('/gallery3/rss/feed/gallery/album/my_var'); Any help would be much apreciated. Thanks, Sion.

How can i do that? Best Regards Mozack Can someone please tell why this is not working in the browser. Here's my code: <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> <script type="text/javascript"> var secondaryHeadings = document.getElementsByTagName("h2") alert(secondaryHeadings[0].innerHTML); </script> </head> <body> <div> <h1> Main Headline </h1> <h2> Sub-Headline</h2> </div> </body> </html> I am trying to manipulate a an image gallery that functions well. Now, I have the ability to pull information from a user's preference pannel and need to place it in the an href="" // And other information in each of the "src" | "url" | "alt". Any ideas would be truly helpful. This is what I am working with at the moment and it doesn't work (obviously because it is adding code inside a span). Here is what I am starting from: [CODE] var title01Span = document.getElementById('title01Span'), //Finds the id that I want prefs = new gadgets.Prefs(), // Pulls from the user's preferences yourtitle01 = prefs.getString("title01"); // Pulls the correct string from those preferences title01Span.innerHTML = yourtitle01; // replaces the span.id with that text but I need to be able to do this in the src / href / url / etc. [CODE] Thank you so much! I seriously could use as much help as possible! Hello, recently I have been to many government websites where I have noticed that the programmer has used window.open() method in JavaScript to link to different pages instead of using <a> tags! I was just getting curious to know whether it is normal or has it been used due to security concerns(if any, I don't know)? Any comments? Hello, I run a online gaming website, and I'm having problems with certain websites iframing our games. Actually I'm ok with iframing, as long as they include the banner ad located just beneath our games. But often times unscrupulous webmasters will iframe only the game, preventing us from generating any revenue from the banner ad (and costing us additional bandwidth charges). I'm hoping to find a way to detect the dimensions of the iframe, so that I may dynamically resize the game, in order to include the banner ad within the iframe. Does anybody know how to extract the "height" and "width" attribute values from an <iframe> tag sitting on a different site? Regards, Steve Hi all, I'm having a bit of a problem..

if its possible to make it do both in 1 function, please show an example. if you have to use 2 functions, then also show me an example. ANY help is GREATLY appreciated! Hi, My webpage can work normally in IE but not in Safari(e.g. when I clicked on some buttons like 'Delete' button, the page opened in Safari stays the same while it should delete the object chosen). When I tried debugging on Safari, after clicking the 'update' button, this message error appeared: "TypeError: Result of expression 'this.form.fireEvent' [undefined] is not a function". I believe this code makes the incompatability between the 2 browser: Code: function DeleteClick()
{
var frmSWO = document.getElementById("form");
var answer = confirm("Do you really want to delete?")
if (answer != 0)
{
frmSWO.action = "/domsWeb/mtd/doms/web/operation/eDepotMNR/controller/manageWorkOrder/DeleteJobOrImage.do";
frmSWO.method = "post";
this.form.fireEvent('onsubmit');
frmSWO.submit();
}
}
Any suggest how should I amend the script for it to work on 2 browser concurrently? Thanks all! |
