JavaScript - Help! Using "for" Loop To Assign Link Url's To Dynamically Created Divs Not Working!
I'm building a t-shirt shop whose interface includes a gallery of designs in an IFrame. When the user clicks on a design, a dedicated page is loaded into the IFrame which shows all the available products associated with the design the user clicked.
I've put each design's image and associated page as the first and second elements of a nested array, and am using a for loop to then load all the images into the page that's shown in the IFrame when the web-site loads. It's looking beautiful, but here's the rub I've been stuck on for two days now with no solution in sight... The array, "designImages", has 37 elements (ie. designImages[0]... designImages[36]). When I click on a design image on the page, any design image, the browser (all browsers, so I can't blame Microsoft for this one ), loads the page for design #36. I've tried all sorts of things, but still cannot tell if the issue is because the dynamically generated divs are being reassigned the value [36] after the for loop's executed, or if the div id's are okay but somehow the code is rooting for [36], the last element of the array anyway. I need someone's help in enabling a click on #4 to load the page for #4, etc, etc. Here's the code below. Thanks. Code:
/* designImages[x][0] = the image source on the page;
* designImages[x][1] = the destination url on clicking the image;

Similar TutorialsHad no replies to my previous post ! http://www.codingforums.com/search.php?searchid=6740324 I have tried to manipulate some (pretty complex) code for reading external code seen here on CF but there was nothing on doing this in a "For Loop" so had no real success Can anyone assist ? Most Kind Function to Read-In External "XML" datafiles on For Loop Can anyone help ? see: http://www.jcsweb.biz/mef/AnimGIF/XMLtemp_04c.htm for required output Javascript Function required: To read in 7 successive "XML" files (not pure XML format & held in "Gallery/Data" external dir in a For Loop: (US_SUMlev_2008.xml,US_SUMlev_2009.xml.....to US_SUMlev_2014.xml) These XML then succesively update a string variable "strXML" which forms the "data" populating a time-series chart. "strXML" then acts as the input to "setDataXML" which is the Chart's data update method (?) The sequential updating of "strXML" in a For Loop should the create a psuedo-animation effect in the chart. My code (see below in edited format or view source at above URL) will achieve what I want but the "strXML" variable update is currently HARD-CODED (rather than read from the XML files held in external directory "Gallery/Data" ). The required function will also need to strip out all linbreaks ("\n") from the external XML files in order to produce a single line of stringtext: eg HTML Code: Code: <chart animation='0' caption= 'Chart1' yAxisName=' % change' ><categories> <category label='2008' /> <category label='2009' /> <category label='2010' /> <category label='2011' /> <category label='2012' /> <category label='2013' /> <category label='2014' /></categories><dataset seriesName='zGDP_u' color='6600CC' renderAs='Column' dashed='1'><set value='0.000000' /></dataset><dataset seriesName='zCPI_u' color='0000DC' renderAs='Line' ><set value='0.000000' /></dataset><dataset seriesName='ERIb_u' color='FFAA26' renderAs='Line' ><set value='0.000000' /></dataset><dataset seriesName='RSH_u' color='FF0066' renderAs='Line' ><set value='0.000000' /></dataset><dataset seriesName='zER_u' color='00FF00' renderAs='Line' ><set value='0.000000' /></dataset></chart> The sequential updating of "strXML" is also NOT yet done in a For Loop but a fixed timing Animate() function which successivley activates the generateXML_200?() on a timedelay. Summary: Required Runstream in Function For Loop: Loop1: Read-in "Gallery/Data/US_SUMlev_2008.xml", strip out "\n", update strXML (& thus setDataXML) & update chart1 Loop2: Read-in "Gallery/Data/US_SUMlev_2009.xml", strip out "\n", update strXML (& thus setDataXML) & update chart1 etc etc until Loop7: Read-in "Gallery/Data/US_SUMlev_2014.xml", strip out "\n", update strXML (& thus setDataXML) & update chart1 If there was a way to "Freeze" and "Restart" this above function (ie pause the read-in of the next XML) as in current code that would be mighty fine too.

Code: window.onload = initForms;
function initForms(){
for(var i=0; i<document.forms.length; i++){
document.forms[i].onsubmit = function(){
return validForm();
}
}
}
Hi, this is the first part of a long code and I have three questions wondering if anyone could help me.. 1. What is the benifit of having the above code with "window.onload" and "for loop" and loop through the forms if I only have ONE form in html? 2. What is this line of code "document.forms[i].onsubmit" saying? Does it mean "Execute function() when submit button within form[i] has been pressed?" 3. function() - Does this empty function mean "run every following function below"?? Thank you!! First post here so... I have a few functions called by a form. Two examples are onclick in a form input and onkeyup in a form button. Code: function checkUsernameForLength(whatYouTyped) {
var fieldset = whatYouTyped.parentNode;
var txt = whatYouTyped.value;
if (txt.length > 2) {
fieldset.className = "welldone";
return true;
}
else {
fieldset.className = "";
return false;
}
}
Code: onkeypress="checkUsernameForLength(this);" There are a couple of the above "validation" functions. Each sets an input fieldset's class. Code: function verifyit() {
var fieldsets = document.getElementsByTagName("fieldset");
var i=0;
while (i<count(fieldsets)){
if (fieldsets[i] != "") {
i++;
document.form.submit();
}
}
}
Code: onclick="verifyit()" The function above is where I'm having the trouble. I want to iterate through the fieldsets and make sure each class isn't blank before allowing the button to submit the form. I get an "object expected" error when I trigger the "verifyit" function with ie if it helps. I appreciate any input, thanks in advance for any help. 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! Hey guys, This is my first time ever posting in a programming forum so please be nice! :) I'll admit right away that this is for a homework assignment, but I really did try to solve it myself before I decided to post here. The instructions are to have a confirm box pop up when links with the HTML class value "external" are clicked. If the user clicks "OK" they should be directed to the linked page. If they click "Cancel" they should not be directed anywhere. Here's my code: Code: function checkClass() {
var links = document.getElementsByTagName("a");
for ( var i = 0 ; i < links.length ; i++ ) {
var link = links[i];
if (link.className == "external") {
link.onclick = clickHandler();
}
}
}
window.onload = checkClass;
function clickHandler() {
if (confirm("You clicked an external link. Do you really want to leave this site?")) {
return true;
}
return false;
}
The problem is that the confirm box is triggered on page load and not on link click. I know I wrote Code: window.onload = checkClass; but how else should I call the function? I thought Code: if (link.className == "external") would keep it from going as far as to the confirm box until an external link was clicked. Thanks for pointing me in the right direction, Johanna Hello, how could I run an external (but still on the same server) ".js" file from a <a href> or a button? Is it possible and how? Thanks. If you need any details just ask. 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! 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? 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. 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'; } Hi, i have the following html page <html> <head> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script> </head> <body> <input type="text" id="input1" /><br /> <iframe id="textEditor" name="textEditor"> </iframe> <script type="text/javascript"> $(document).ready( function() { textEditor.document.designMode = "on"; textEditor.document.open(); textEditor.document.write('<head><style type="text/css">body{ font-family:arial; font-size:13px;}</style><body>Hi User<br /><br /><span style="font-style:italic;">### Write your message here ###</span><br /><br />Thanks,<br /></body></head>'); document.getElementById("textEditor").contentWindow.addEventListener('focus', OnFocus, true); $("#input1").focus(); } ); function OnFocus() { textEditor.document.body.innerHTML = textEditor.document.body.innerHTML.replace('<span style="font-style:italic;">### Write your message here ###</span>', ""); document.getElementById("textEditor").contentWindow.focus() } </script> </body> </html> Now press on the tab key when the page loads (You should see focus on the textbox field) and you can see that the iframe text editor (WYSIWYG) has no focus... On firefox it works... How can i give it focus on chrome? First I have a performance question. Which would be better: Load a full table from the database first and display a portion with a "Show More..." link --OR-- Load just the small portion with a "Show More..." link and then do an ajax call to load the rest of the table? And secondly, I sort of know how to do the second option but it can get a bit complicated. You need to know the offset of which to search a database to load the rest. and the "append" that to the table. If I do the first option, it seems a bit more easier but I can't seem to come up with the logic. How would I truncate a table showing only a few entries and have the rest of the table hidden while having a link that shows the rest of the table when clicked? Thanks in advance. . . My website with "ideas for education" will have two sitemaps -- a diagram, and a text-outline -- each located in the left i-frame, with links opening in the right i-frame. My homepage promises that each sitemap will "show where where you've been (green links), where you are (red highlighting), and where you can go (blue links) in your explorations." . . The diagram-sitemap uses "swap images" (with code written by Dreamweaver) and 14 gifs, each with a red rectangle behind one of the 14 main links. (But it doesn't have green visited-links to show "where you've been.") . . In my text-sitemap, red-highlighting a visited link was easy, again by using DW's javascript tools. But this makes every visited link retain its red background, until the page re-loads. My goal is to red-highlight ONLY the last-visited link, to clearly show "where you are" in the sitemap. . . In one attempt to remove the red, I tried forcing a page-reload onMouseDown (with DW's "Go to URL") but DW refuses to recognize the sitemap's iframe (named "left") so it can only load the text-sitemap into a top-frame instead of the left iframe of its frameset. And this reload would be an awkward solution anyway, especially if a user has scrolled the page so the cursor would have to be moved back to the link for the onMouseUp part of clicking a link. . . A more elegant solution, found in a web-search, claims that "You can put an onclick event in all your links and then when the user clicks on a link, you can use the onclick event to call a function that changes that link's color to, say, green; and then uses the 'links' array to change all the other links to another color. The 'this' keyword can be used to identify the current link." . . This sounds promising, and JS-experts will see the two bold steps -- to "put..." and then "use..." -- and say "this is easy." But for me, doing these steps is a mystery I haven't solved. Some clues are below, gathered from various sources, but I don't know how to put it all together. A solution requires that everything is coded exactly the way it must be, with no mistakes, and I don't know how to do this. . . Here are some "pieces of the puzzle" that might be useful: . . Each sitemap has three areas, symbolized by colored page-backgrounds -- light blue & light green & yellow -- DDEEFF, DDFFEE, and FFFFBB. The js-code below, made in DW, works to change a link with red-background (from a previous link-click) to blue-background (onMouseDown) and back to red-background (onMouseUp). Code: <a href="blue1.htm" target="self" onMouseDown=" MM_effectHighlight (this, 1, '#DDEEFF', '#DDEEFF', '#DDEEFF', false)" onMouseUp=" MM_effectHighlight (this, 4000, '#DDEEFF', '#FF9999', '#FF9999', false)"> blue, then red</a> . . This works. But the challenge is to change OTHER links (not "this") from red to a color (blue, green, or yellow) that matches the page-background of the area where each link is. And for this I'm failing in two ways. First, I don't know how to make the link being clicked ("this") change the background-color of other links, by ""using the 'links' array to change all the other links to another color." Second, if I want to make three color changes (from red back to blue, or to green, or to yellow) the triple-change code below, which is the code above but with the onMouseDown line repeated 3 times, doesn't work in DW: [a comment added January 7: I've now abandoned this triple-change idea, and instead I want all links changed (onMouseDown) to a GOLD background-highlighting in a link-rectangle that surrounds each of the 14 main-topic links, but not the 40 sub-topic links.] Code: <a href="blue1.htm" target="self" onMouseDown=" MM_effectHighlight (this, 1, '#DDEEFF', '#DDEEFF', '#DDEEFF', false)" onMouseDown=" MM_effectHighlight (this, 1, '#DDFFEE', '#DDFFEE', '#DDFFEE', false)" onMouseDown=" MM_effectHighlight (this, 1, '#FFFFBB', '#FFFFBB', '#FFFFBB', false)" onMouseUp=" MM_effectHighlight (this, 4000, '#DDEEFF', '#FF9999', '#FF9999', false)"> blue-green-yellow, then red</a> . . Imagine that two links (blue0.htm, blue1.htm) are in a blue-background area of the text-sitemap, while two other links (2,3) are in a green-background area, and two links (4,5) are in a yellow-background area. By copying the code I found in another page, I think the code below might describe the links-array I want. But this raises two more problems: Third, the array probably contains errors or omissions. Fourth, even if it was correct, I don't know where to put it: in the head section? body section? inside the js-code for a link? if yes, would I have to repeat this code for each of the 14 main links, or should I write it once (with a name) and then "call up" this name for each of the 14 links. These are things an expert will know, but I don't. Code: <div class="box_broadstyle"><script> var linksArray = new Array(); links[0] = "blue0.htm"; links[1] = "blue1.htm"; links[2] = "green2.htm"; links[3] = "green3.htm"; links[4] = "yellow4.htm"; links[5] = "yellow5.htm"; </script></div> . . And I think the code below might be useful to make a "for loop" to control the triple-change by telling the browser which links (0 and 1) should have blue-highlighting (ending with #DDEEFF), and which (2,3) should end with green, and which (4,5) will be yellow. But... Fifth, I don't know if this code is correct or (a tougher challenge) where to put it so it will be functional. Code: for (y=0;y<=1;y++) for (y=2;y<=3;y++) for (y=4;y<=5;y++) . . Thanks for your patience in reading through this question, which is long because I've tried to clearly describe my goals and what I think might be parts of a solution. Any help in solving these mysteries (first, ... fifth) will be greatly appreciated. CraigR Hi, 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. Thank you I have this javascript where the user enters text in a text field. On submit, the user's entered text validates for "value must be one of."

Hi guys, I have a JS calculator on my website which is basically a load of radio buttons that the user clicks and as they do so a price is calculated in their view. At the moment - the price box starts with a blank box but is essentially "0". Then, as the user select an option, the price appears and then starts to calculate when more than 1 is pressed. All I want to do is have the price start at "300" instead of a blank box or "0". Then the rest of the options calculate onto that. I have tried a variety of ways to achieve it and seem to be missing something! I am pretty new to JS although do have a basic understanding ..... clearly not enough to do this thou! lol Basically imagine 300 is the initial price. That only gets charged once ... Here's my code .... In the <head> Code: <script type="text/javascript">
function getRBtnName(GrpName) {
var sel = document.getElementsByName(GrpName);
var fnd = -1;
var str = '';
for (var i=0; i<sel.length; i++) {
if (sel[i].checked == true) { str = sel[i].value; fnd = i; }
}
return fnd; // return option index of selection
// comment out next line if option index used in line above
// return str;
}
function chkrads(rbGroupName) {
var ExPg = [
[0,''],
[100,"1 extra page"],
[200,"2 extra pages"],
[250,"3 extra pages"],
[300,"4 extra pages"],
[350,"5 extra pages"]
];
var ExEm = [
[0,''],
[10,"1 extra email"],
[20,"2 extra emails"],
[30,"3 extra emails"],
[40,"4 extra emails"],
[50,"5 extra emails"]
];
var ImgBun = [
[0,''],
[10,"3 extra image"],
[20,"5 extra images"],
[30,"7 extra images"],
[40,"10 extra images"]
];
var rbtnGroupNames = ['extrapages','extraemail','imagebundles'];
var totalprice = 0;
var tmp = ''; var items = [];
for (var i=0; i<rbtnGroupNames.length; i++) {
tmp = getRBtnName(rbtnGroupNames[i]);
if (tmp != -1) {
switch (i) {
case 0 : totalprice += ExPg[tmp][0]; if (tmp > 0) { items.push(ExPg[tmp][1]); } break;
case 1 : totalprice += ExEm[tmp][0]; if (tmp > 0) { items.push(ExEm[tmp][1]); } break;
case 2 : totalprice += ImgBun[tmp][0]; if (tmp > 0) { items.push(ImgBun[tmp][1]); } break;
}
}
}
document.getElementById('QUOTED_PRICE').value = totalprice;
document.getElementById('ITEMS_SELECTED').value = items.join('\n');
document.getElementById('PRICE_IN_VIEW').innerHTML = totalprice;
}
function validate() {
// add any required validation code here prior to submitting form
var allOK = true;
// if any errors found, then set 'allOk' to false;
return false;
// after testing with validation code, change line above to: return allOK;
}
</script>
