Hi! I have a javascript in the head of the document which has a variable named "ref2" ... ref2 is already working as I can see its value working in another function. I need to send this variable as the value of a hidden field in the form which is in the body of the document. This is my JavaScript Code: Code: function WriteContactFormStatement1 () {
var ContactFormValue = ref2;
document.write('<input type="hidden" name="UReferrersName" value="' + ContactFormValue + '" />');
}
var WriteContactFormStatement = WriteContactFormStatement1 ();
And at the end of my form, before the submit button, I have the following code: Code: <!-- START -- Javascript to print the statement for UReferrersName --> <script language="JavaScript" type="text/JavaScript"> //WriteContactFormStatement(); document.write (WriteContactFormStatement); </script> <!-- End -- Javascript to print the statement for UReferrersName --> When I execute the form, it doesn't work the way it should, plus, gives me a word "undefined" next to the "Submit" button ..... Please help !... - Xeirus. As of right now I have a code that will work in IE but wont work in FireFox...go figure. Basically what I want to have happen is when you type in an area code it will provide an output in a predetermined area of the page. For Example: Input- 512 Output - Austin, TX The code that I have doesn't work with firefox and I was just wondering if there was a code that would allow that to happen. Thanks! Hello I have a piece of javascrip that refreshes the page: ---------- Code: <script type="text/javascript">
<!-- Begin
function reFresh() {
location.reload(true)
}
/* Set the number below to the amount of delay, in milliseconds,
you want between page reloads: 1 minute = 60000 milliseconds.
2 minutes = 120000 milliseconds 5 minutes = 300000 milliseconds*/
window.setInterval("reFresh()",20000);
// End -->
</script>
-------- I am new to javascript and wanted to use an html options menu in order to be able to choose the refresh interval: Code: <SELECT NAME="refreshtime"> <OPTION VALUE="60000">1 min</option> <OPTION VALUE="120000">2 min</option> <OPTION VALUE="180000">3 min</option> <OPTION VALUE="240000">4 min</option> </SELECT> I know that I have to pass a variable to the function. I have tried several variations but none have worked. I have mostly received a "done with errors" warning. Any help would be appreciated. Thanks Zam Can anyone tell me of how to take or assign a javascript variable into php.
I am just starting to learn javascript and was hoping someone might be able to answer my question: var months = "April Showers"; document.write('<p><img src="ad11.jpg"); document.write(" alt="); document.write(months); document.write(">"); document.write(months); How come when I display my output to a browser without the presence of the ad11.jpg file, only the first word (April) in the text string "April Showers" is dispayed where the .jpg file is suppose to be...but the last line displays the entire text string. Hi there, i have one script which is supposed to pop up a new win and after it does write a piece of text in it. This text comes from inside the HTML area: Code: (script)
function popupwin(whichOne) {
var width = 450;
var height = 490;
var left = parseInt((screen.availWidth/2) - (width/2));
var top = parseInt((screen.availHeight/2) - (height/2));
var windowFeatures = "width=" + width + ",height=" + height + ",status=no,resizable=no,location=no,titlebar=no,left=" + left + ",top=" + top + "screenX=" + left + ",screenY=" + top;
newwin = window.open("spSelect.html","spSelect",windowFeatures);
spSelect.document.whichOne.value = whichOne;
}
(calling part in html)
<a href="javascript: popupwin(Souvlaki);"><img src="images/orderbutton.gif" width="100" height="20" border="0"></a>
(new win place where text is supposed to appear)
<input name="whichOne" readonly="readonly" type="text" class="textfield">
window.onload = initAll; function initAll() { document.getElementById("Message").onfocus = focusHandler; document.getElementById("Message").onblur = blurHandler; } function focusHandler() { document.getElementById("helpYou").innerHTML = "<span class=\"helpMessage\">Hey " + theName + "You should add Lasting Flash to your Facebook!</span>" } function blurHandler() { var helpMessage = document.getElementById("helpYou").innerHTML = ""; } function nameHandler(frm) { var theName = frm.firstName.value; } Quote: When I insert theName variable within the span the code completely does not work. I am accessing a text field when the user enters his name and then a small pop up later that includes the users name when another field is clicked on. I have a code which calls a variable which then prints to screen, however I am trying to get the value of a text box to automatically update this variable when I type into the text box. This works : [CODE] <script> var message = "Some Message Here" function thisINIT(){ if (NS) {loop=setInterval("scroll()",55);} else if (IE){loop=setInterval("scroll()",55);} else {loop=setInterval("scroll()",100);}} </script> [CODE] This doesn't [CODE] <script> var message = document.getElementByID(copy_from).value function thisINIT(){ if (NS) {loop=setInterval("scroll()",55);} else if (IE){loop=setInterval("scroll()",55);} else {loop=setInterval("scroll()",100);}} </script> [CODE] This script also uses a CSS but I didn't think it neccessary to get the values in. Any help is,as always appreciated, I have banged my head against the wall for days now !!! Hi world I have this code in my page PHP Code: <iframe name="ff1" src="http://playerplus.co.nu/ipp.php" ></iframe> how i copy the result in this iframe to text or to some variable but from iframe not direct from the URL "http://playerplus.co.nu/ipp.php" Hi, my first question on this forum is I hope a simple one. I have an input text field that I would like to have either the user fill out but also I would like to be able to fill it with text, which I can do, via javascript or a variable which I don't seem to be able to manage. I have tried lots of options, converting to a string first and much more but it will not work, maybe it is a syntax error or maybe I am just doing it plain wrong. I think it should be simple but I have only been using javascript for a few weeks so who knows, hopefully one of you! Here is my code for displaying a variable which does not work: Code: <html>
<head>
<script type="text/javascript">
function myfunction()
var mynumber = 101;
document.getElementById("myinput").value = mynumber;
</script>
</head>
<body>
<p id="demo">Web Page 1</p>
<button type="button" onclick="myfunction()">JS</button>
<input type="text" value="00000000" id="myinput">
</body>
</html>
I would be very grateful for any help. Thanks Simon I get the screen resolution with this script: <SCRIPT language="JavaScript"> <!-- height = screen.height; width = screen.width; document.write(width + "x" + height); var x = ( width + "x" + height); //--> </SCRIPT> Now I have some links below and I want to use bold if the link has the same screen resolution: <a href="page1">800x600</a> <a href="page2">1024x768</a> <a href="page3">1680x1050</a> <a href="page4">1920x1200</a> Supposing my screen resolution is 1920x1200, the result should be: 800x600 1024x768 1680x1050 1920x1200 How do I do that? Thx!! Is it possible to pass the value of a javascript variable through src? For example, instead of... <script type="text/javascript" src="/myfolder/myjsfile.js"></script> ...could I have something like... <script type="text/javascript" src=JS VARIABLE VALUE></script> What would be the syntax for this? Is it even possible? Thank you! SOLVED I am trying to use a php variable in javascript.

Hi, I have a small script that opens a small popup in which to populate a form. What I want to do is include a variable so that a particular PHP page opens. I include where I am at present: HTML page calling JS popup: <input type="text" name="DOCUMENTS" id="DOCUMENTS" onclick="makeSelection(this.form, 'DOCUMENTS');"> JS Code: targetElement = null; function makeSelection(myform, id) { if(!myform || !id) return; targetElement = myform.elements[id]; var handle = window.open("../file_upload.php?dir=CODE", "mywindow","menubar=0,resizable=0,width=400,height=250"); } What I want to be able to do is get it so that the bit of JS that has 'dir=CODE' has a variable called from the HTML page. Is this possible, and if so, could anyone please help me out? Regards, Neil I've been having a hard time with this and was hoping someone here would take a little pity and render me a great service. I'm using a javascript to get the user's timezone and am trying to pass the response to an input field in a php form. With a great deal of trial and error I got a demo working to a point but I'm stuck. Here's what works now: Code: <p id="timezoneInformation" style="text-align: center;">click here</p>
<script src="jstz.js"></script>
<script>
var container = document.getElementById("timezoneInformation");
var showTimezone = function () {container.textContent = jstz.determine().name();};
container.addEventListener("click", showTimezone);
</script>
jstz.js is from Automatic timezone detection using JavaScript The example above is as far as I've gotten. I would like to send the results to a form field to submit to the server. It's probably a lot easier than I'm making it out, but I've had little success and would welcome any help. Thank you. Hi: I got a blank page returned when using javascript within the Frameset. Here is part of my codes: (my javascript part) <script language="JavaScript"> //this function will be used to get the parameter from URL using javascript function gup (name) { name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]"); var regexS = "[\\?&]"+name+"=([^&#]*)"; var regex = new RegExp( regexS ); var results = regex.exec( window.location.href ); if( results == null ) return ""; else return results[1]; } //get the transactionID from the URL var transactionID = gup('name'); //add the transactionID as the URL parameter var url = "../../onetwothree/Approve.jsp?name=" + transactionID + '\"'; var temp = '<frame name=\"onetwothree\" ' + 'src=\"' + url + '>' + '</frameset>'; </script> ---------------------------- (my html part) <frameset rows="0,*" border="0" frameborder="0" framespacing="0"> <frame name="onetwothreeFrame" src="../onetwothree/abcd.html" marginwidth="0" marginheight="0" scrolling="no" noresize> <script language="JavaScript"> document.write(temp); </script> </frameset> Gonna be asking a few Q's about a quiz javascript i'm making. I'm pretty new to JS. I have this, a select box, in the body. Code: <div align="center"><center><p><strong>Your response:</strong> <select
name="theresponse" size="1" onChange="responses()">
<option value="-----">----</option>
<option value="a">a</option>
<option value="b">b</option>
<option value="c">c</option>
<option value="d">d</option>
</select>
Then the relevant bit of script lower down Code: var loop=0
function responses(){
loop++
var temp2=document.instantquiz.theresponse
var temp3=temp2.options[temp2.selectedIndex].text
if (temp3!=solution[whichone]&&temp2.selectedIndex!=0)
document.instantquiz.thesolution.value="Sorry, the correct answer is "+solution[whichone];
else if(temp2.selectedIndex!=0)
document.instantquiz.thesolution.value=compliments[whichone];
}
I want to add 1 to 'loop' (so that people can't score twice etc.). The problem I have here is that loop just doesn't want to go up. I've tried all sorts of things like doing it under a new variable, and even putting a new function up, all in vain. Why doesn't it work? =s I am working on a commenting system and I was able to get it working by using 5 separate scripts, which are exactly the same, except for having slightly different variables. I had to repeat (copy & paste) the js function 5 times in the html <head>, and only allow for 5 posts per page. Which works fine. But, I thought maybe I could replace it with a single function that includes an iteration counter that changes the variables automatically? Here's what I have now (below), if you think this can be easily turned into 1 function with iteration counter, please let me know how, as I am new to js. I already have the iteration working on the php end, but, I just couldn't figure out how to do it for the javascript. Code: <script type="text/javascript">
$(function() {
