JavaScript - Writing String Value To A Separate Iframe Using Onmouseclick
Hello,
I am currently trying to create a simple form based web-page (uploaded here) that creates a query for a WMS (Web Map Service). Seeing as how I am still new to programming, I was hoping that you could help me . The page consists of about 10 different forms, which are all put together in a (string) variable named "compiledQuery" in a function named "compileRequest" which is activated via a button. I would like to print out this variable on the page so that the users can see the query for themselves. After doing some research I came to the conclusion that the best way to do this would be via an iframe (I do not want to use a pop-up). The function I use to do this is: Code: function printRequest()
{
var query_frame = document.getElementById('frame_compiled');
query_frame.document.write(compiledQuery);
}
"frame_compiled" is the name of my iframe: Code: <iframe name="frame_compiled" width="400" height="125"> </iframe> I know that "compiledQuery" has been assigned a value (I used an alert with the value). Hence, I also know that the "prinRequest"-function works on principle... However, it seems as if I am having problem with retrieving the name of the iframe to the function (I tried doing an alert with the value, it was returned as null). So, I suppose my question is this: How do I properly retrieve the value of the iframe, and am I on the right way using document.write to show the value of "compiledQuery" to the users? Or should I use another way of doing this completely? I think I have looked through a hundred different tutorials and guides online, I just can't seem to find any hints to this problem... Any help would be greatly appreciated Similar TutorialsHi Guys I'm struggling to find out why the iframe is not being populated with a selectbox containing the album names from an XML file. majority of the code is working fine and the "alert(s)" function works perfectly and displays exactly the html I would like it to but the bits in bold are not working and are not writing the html to the iframe. (please note, this code is only supposed to work in Javascript) . Thanks Code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Frameset//EN"

Hi, I have read (and been told) that the current standard/fashion is to have separate files for html, css and javascript but nobody has ever said why that is... it would seem to me to be easier to keep everything in one file, but there must be advantages to separating them out. Does anybody feel like breaking them down for me? thanks in advance. I want to make separate js and html files from my toggle.htm file: Code: <html>
<head>
<script type="text/javascript">
function toggle() {
var ele = document.getElementById("toggleText");
var text = document.getElementById("displayText");
if(ele.style.display == "block") {
ele.style.display = "none";
text.innerHTML = "show";
}
else {
ele.style.display = "block";
text.innerHTML = "hide";
}
}
</script>
</head>
<body>
<a id="displayText" href="javascript:toggle();">show</a> <== click Here
<div id="toggleText" style="display: none"><h1>peek-a-boo</h1></div>
</body>
</html>
My togglejs.js file looks like this: Code: function toggle() {
var ele = document.getElementById("toggleText");
var text = document.getElementById("displayText");
if(ele.style.display == "block") {
ele.style.display = "none";
text.innerHTML = "show";
}
else {
ele.style.display = "block";
text.innerHTML = "hide";
}
}
My togglehtm.htm file looks like this: Code: <html> <head> <script type="text/javascript" src="toggle.js"></script> </head> <body> <a id="displayText" href="javascript:toggle();">show</a> <== click Here <div id="toggleText" style="display: none"><h1>peek-a-boo</h1></div> </body> </html> What changes should I make. Please help. Hey all, So basically, what I effectively want is a dropdown menu, but without it dropping down. Let me put it a different way, I have my top links, and a space underneath them. What I want is for if you move your mouse over one of the links a new set of links relative to that one will appear in the box below and will remain there until the mouse is moved over another main link. Is this possible? Thanks Hello. I am opening a new small window through javascript. Here is the code: Code: <script type="text/javascript">
function openwindow(id) {
var left = (screen.width/2)-350;
var top = (screen.height/2)-240;
var mywindow = window.open(" map.asp ?location="+id,"mywindow","menubar=0,resizable=0,width=700,height=400,left="+left+",top="+top+"");}
</script>
But on the same page I have another link for a new window which is essentially the same code: Code: <script type="text/javascript">
function openwindow(id) {
var left = (screen.width/2)-350;
var top = (screen.height/2)-240;
var mywindow = window.open(" pofull.asp ?poid="+id,"mywindow","menubar=0,resizable=0,width=700,height=400,left="+left+",top="+top+"");}
</script>
As you can see in the red text, one link should open map.asp and the other should open pofull.asp... but they BOTH open in pofull. So I have tried to change the function name for one of them but then it doesnt work at all. I am quite confused here. I have tried everything to separate the two scripts but nothing has worked. Can someone help? Hi On my web page I have 3 seperate catorgories with 2 drop down lists in each, the first dropdown list in each catergory is for "county" here is a snippet of the code Code: function fillCategory(){
addOption(document.drop_list.Category, "bedfordshire", "Bedfordshire", "");
addOption(document.drop_list.Category, "berkshire", "Berkshire", "");
addOption(document.drop_list.Category, "buckinghamshire", "Buckinghamshire", "");
addOption(document.drop_list.Category, "cambridgeshire", "Cambridgeshire", "");
I wanted to know if it is possible to use "list.js" to populate all 3 county dropdown lists or would I need "list.js" "list1.js" etc etc Hi, I'm fairly new to javascript & am trying to learn it using best methods. I have been using various books & some video tutorials, such as lynda.com. I've noticed when I do google searches for example tutorials, 9 times out 10, the javascript has been coded into the html file. As a newbie I find it takes a very long time to redo the coding into the separate .js file. And if the coding is relatively complex (and most of it appears that way to someone new to this) I can't get it too work using a separate file for the javascript. I wanted to ask anyone very familiar with this, their suggestions regarding good places for tutorials where the .js file is separated. Apparently there are advantages to having it separate and it's considered best practices from what I've come to understand. Also most of the results from google searches pulls up out-dated coding and/or tutorials that suggest you should already understand what is being referred too. I'm trying to avoid learning it the wrong way. I'm willing to put in the effort, however I don't want to pick up bad habits. Any help is very appreciated. If this was not as clear as I intended it to be, please ask any specifics and I'll try my best to answer. -Todd Hi, I'm writing a page scraper in javascript which involves loading a page to scrape, detecting when the page has loaded successfully and then scraping the data. I can get the 'page loading detection' to work if I load the page in a sub-frame. But this is no good as some sites include frame-buster code which breaks my scraper and I cant get any of the framebuster-buster solutions to work. So instead I decided to look at loading the page in a separate tab. Does anyone know how to reliably detect when a page has finished loading in a tab please? I am using Firefox only and I dont mind if the solution requires some extension or greasemonkey script (I have already added the configuration/commands to allow access to pages from different domains). The code below shows an attempt. It sometimes detects when the initial page has loaded but when I press 'submit' it doesnt detect the second loading. Thanks. Code: <html>

Hi, I was working on this problem that asks me to return an array of scores for each string (only for its content part, not URL) in the global variable, which is an array. For example, alert a score of 0 if the string z is not found, 1 if found once, and 2 for twice. My problem is that I can get the code to alert if it has found the word (ex. "the"), but I cannot manage to : a) Assign separate scores for each string. b) Make the search case insensitive i.e. "the" will appear in 0,1, but not in 2, where it is capitalized I would appreciate any help! [CODE] var c = ["[www.facebook.com] Facebook is the best social networking site to coccent with your friends. ", "[www.google.co.uk] Google is the worldwide search engine. ", "[www.bbc.co.uk] The best news source for starting your day. "]; function findScore(z) { for (var i=0; i<c.length; i++) { var a = c[i].toString(); var b = a.search(z); if(b>-1) { alert (z + " found in array " + i); } } } findScore("the"); [CODE] Sorry for not being able to wrap the code! so, I can pass a value from a select list to another function which then decides which function to call, but I want to cut out the middleman, and make the values the function calls, and call them directly on the onchange... I imagine something like this: Code: <select id="select" onchange="this.value">
<option selected value="function1()">Funtion 1</option>
<option value="function2()">Function 2</option>
<option value="function3()">Function 3</option>
</select>
is it possible? HTML5&JS-Game-1 Large JS Into Separate JS Files? Hi, I am a C++ game programmer who attempted to make an HTML5/JS game. Game turned out great (except for some performance issues on old computers). Although the game is good, I am terribly embarrassed about the source. Source is HTML5/JavaScript and its one giant, ugly, and confusing HTML file. I've been researching on Google how to split the 1 large HTML file into smaller separate *.js files but can not get it working. Here is the URL link to the game's folder on my web site: http://16bitsoft.com/T-Crisis3AI--HTML5/ I've tried to split the one HTML file into smaller separate *.js files. Had a "Logic.js" file with all logic global variables and functions in it and I loaded the "Logic.js" file (I think) into main HTML file but the main HTML file can't locate the logic variables and functions??? If your a Jedi Master Ninja Assassin HTML5/JavaScript coder then please try to help! Thanks!

This works exactly as I need. What I'd like to do is the following: 1) Open a URL (e.g. google.com) in a hidden iframe, then 2) Redirect the visitor to a different URL (e.g. yahoo.com) in a full-screen iframe 3) The address bar of the full-screen iframe should be my domain (obviously!)

I've been beating my head against the wall today trying to figure this out, and I'm fresh out of ideas. If you can help, you'll have some serious gratitude and good karma thrown your way! Best wishes, and thanks in advance, Paul Is there a way to resize an iframe dynamically so that you never get the scroll bar and essentially hide that there is an iframe? Better integration really. Basically I want to iframe a forum into my site so that the design down the sides and top which my friend does using iweb are not messed with. We have a central area which can be longer or shorter depending on the forum. Hi there everybody, I've got this problem which I can't solve myself... I've got a website which has 3 colums and is hosted on domain1.com. in the right column I've got an Iframe which loads content from domain2.com . this content are some textboxes and a datepicker tool. if I press the 'search'-button in this Iframe I would like to refresh the mainpage (from domain1.com) so that another Iframe appears in the middle column. in this column i would like to load a new form from domain2.com which contains the values that I've put in in the form from the right Iframe. Unfortunally I can't get this to work... Will somebody please help me? Hello everyone, I'm very new to Javascript, and I'm trying to build a simple webpage with frames with navigation links that open in other frames. I have three frames in the main part of my webpage, A, B, and C. Frame A is the header, Frame B is where I keep the links, and Frame C is where I want the links to display. I'm trying to get the links in Frame B to work both as text links and as radio button links. So far, I have managed to get the text links to open in Frame C as I wanted to, but when it comes to the radio buttons, I encounter a problem. The radio buttons do open as links... Except, they open in the frame they're contained, Frame B, rather than in Frame C like I want them to. Does anyone know how I might fix this problem? Is the coding completely wrong or is it just a simple mistake I've overlooked? Here is the relevant code: This is the code for the main page with the frames: Code: <html> <frameset rows="100,*"> <frame src="Hello.htm" NAME="A"/> <frameset cols="25%,75%"> <frame src="Linklist.htm" NAME="B"/> <frame src="Start.htm" NAME="C"/> </frameset> </frameset> </html> And this is the code for my links: Code: <html>
<head>
<SCRIPT LANGUAGE="JavaScript">

Any and all help would be much appreciated. This has me really stumped. Thank you for your time! Hey everyone. I'm looking for a tutorial or open source script to accomplish the following tasks: 1 - Accordion style vertical list that expands element (Film # and description) when "+more" link is clicked, and closes the previous open film and description. 2 - Activation of "+ more" shows a photo in separate div, and hides the previous photo that was visible in this separate div. I've attached a mockup photo of the idea I need to execute. Seems like a simple idea, but I have not been able to find a similar example/tutorial online. If anyone can point me in the right direction, that would be greatly appreciated. Thanks. Hey all, I have a simple example below showing how when I pass in the value of the value attribute of option node, and then use if operator to check whether parameter is a string or not, even though it's a string, it converts it to false boolean and triggers the else statement rather than calling a function: Code: <body> <select> <option value="createMsg">Add Message</option> <option value="removeMsg">Remove Message</option> </select> </body> Code: var menu = {
handleMenu : function(callback){
if(callback === "string"){
menu[callback]();
}
else {
console.log("Issue occurred")
}
},
createMsg : function(){
var content = document.createTextNode("Please give additional information."),
heading = document.createElement("h1");
heading.appendChild(content);
document.body.appendChild(heading);
},
removeMsg : function(){
}
}
document.getElementsByTagName('select')[0].onchange = function(){ menu.handleMenu(this.value)};
callback should be a string so why is it saying otherwise? Thanks for response I have used iframes for my site and found various javascripts so when a person clicks on say the audio page he http://www.krillmeed.com/index.html it takes them to the audio page but will load it into the index.html page. The problem is, especially with search engines, to point to that page, this is what the URL looks like to send someone to that page: http://www.krillmeed.com/?frame=0&sr...m%2Faudio.html which is not very clean at all, this is the javascript that i found that at least works: Child iframe script: Code: <script type="text/javascript">
(function(){
var qstr = '?frame=0&src=' + encodeURIComponent(location.href),
lre = new RegExp('^' + location.protocol + '//' + location.hostname + '(()|(/)|(/index.html)|(/index.php))(()|(\\' + qstr + '))$');
if (!lre.test(parent.location.href)){
top.location.href = '/' + qstr;
}
})();
</script>
Parent iframe Script: Code: <script type="text/javascript">
(function(){
function getQval(n) {
if(typeof n !== 'string'){
return null;
}
var r = new RegExp('[?&;]' + n + '=([^&;#]*)'), m = location.search;
return (m = r.exec(m))? unescape(m[1]) : null;
}
var f = getQval('frame'), s = getQval('src');
if(f && frames[f] && s && s.indexOf(location.protocol + '//' + location.hostname + '/') === 0){
frames[f].location.href = s;
}
})();
</script>
Is there a "cleaner" way of doing this? This was an old code, i have yet to find a more modern one. Thank you in advance. I have a form where users will be making a selection in a drop down box. I need, essentially, to store two values: the first value is the actual value assigned with each drop down item (their label, basically), and the second value being a completely separate value that will change based on what they chose from the drop down box to begin with. Example: Drop down box contains selections A, B, C, D. User selects A, I need to keep the original dropdown box's A value in tact for the dropdown box's value, and then store a 1 in a hidden textbox. User selects B, a 2 is stored, etc. Both of these values will be e-mailed, hence the reason I chose a hidden textbox to store the second value. Additionally, I don't want the user to see the second value on the form itself. If there's a better way to accomplish this, please let me know. Hi, Not sure if I worded that question right. I have a web page which will display another web page in an iframe. But the content inside the iframe may change while the user interacts with it so I need to be able to resize the iframe height from code on the page inside the iframe. Any tips on how I can do that? I am using php and javascript. Thanks. |
