JavaScript - Looking For A Genius To Solve Variable Prob
Hello
I'd really appreciate some help please, no other forum seems to have an answer for this. Example : I have a file called values.asp and in that file are 100 different variables all assigned a specific number. I also have a results.asp file or a simple html page. The target is to read a specific variable in the values.asp file and then display it in another asp file or standard HTML file using Javascript's document.write(variablename); method. So in other words, i wish to fetch a specific variables value from values.asp and show it in another asp file or a simple html file using javascript. Your help will be very much appreciated. Thanks! Ron Similar Tutorialsthe title kind of sums it up... if I have an array of equations (I'm guessing they should be strings but they don't have to be) and a user-defined variable can that variable be used for the "x" in the equations? I already did the easy part ... Code: <!DOCTYPE html>
<html>
<head>
</head>
<body>
<input onkeyup="solve(this.value)" /><br>
<input id="box0" /><br>
<input id="box1" /><br>
<input id="box2" /><br>
<script type="text/javascript">
var equations=["(x*9/5)+32","x+273.15","x-50*(8/13)"]
function solve(val){
for (var i = 0; i < equations.length; i++) {
document.getElementById("box"+i).value= //ummm...
}
}
</script>
</body>
</html>
I am getting an error, in IE only (7 and 8). Firefox, Safari and Netscape work fine. The problem is with older code, that I have not worked with. (Owner just noticed it, so now I am stuck fixing it.) The code is bascially a dynamic text box, that when a user starts typing in a product name, it displays a drop down list that the user can use to select a product. Once they select their product, a second drop down box displays the various sizes and prices (i.e. Small - $7.50, Medium - $8.50, Large - $10.50.) The error I am seeing in IE is the following: 'name' is null or not an object. Here is the actual select boxes code: Code: <input id="myInput" type="text" style="height:18px; width:190px;" value = 'Type To Find Product' onfocus="this.form.myInput.value='';this.form.products_id.value='';this.form.cart_quantity.value=1;"> <div id="myContainer"></div> </div> </div> <div class="back" style="margin-left:20px;"> <div class="orange" style="line-height:18px;">Size</div> <select name="id[<?php echo WEIGHT_OPTION_ID; ?>]" id="attrib-<?php echo WEIGHT_OPTION_ID; ?>" style="width:114px;height:20px;"> <option value="">Select Product</option> </select> </div> The actual error is occuring here - again only in IE - firefox and other browsers work fine. Code:
var handleSuccess = function(o){
var test=eval(o.responseText);
if(test != undefined){
removeAllOptions(selectbox);
addOption(selectbox,'Choose Weight','');
for (var i = 0; i < test.length; i++){
addOption(selectbox, test[i].name, test[i].id); - here is where it throws an error }
}else{
removeAllOptions(selectbox);
addOption(selectbox,'Select Product','');
}
}
For the life of me, I cannot figure out how to solve this. And I am forced to work until it is fixed, which could be days. No weekend for me unless I can figure this out, or unless someone has a clue that I am missing. Thank you to whomever can help me!!!!!!!! Hello all I'm trying to get this function to check for 10 digits only but alert shows regardless of less / more or exactly 10 digits --- what am I missing? any help on sorting this greatly appreciated. Code: function validate(form) {
if (document.forms[0].callme.checked) {
var phone = document.forms[0].mobile.value; // assign value to var
phone = phone.replace( /[^\d]/g, "" ); // zap all non-digit characters
if ( document.forms[0].mobile.length != 10 ) // chk for 10 digits{
alert("Enter 10 numbers");
return false;
} else {
alert("Yahoo");
}
}

return theWin;
}
and of course onload in body tags <body onLoad="return popmusic('music/music.html')"> any idea's, thanks in advance hey guys, I'm not the quickest running in the race, but I'm slowly learning JavaScript. I'm attempting to use the jQuery iviewer to control the viewing of images. I'm essentially making my own slideshow. In any event, I'm trying to tag a map along with the image. The only way I know of doing this is with standard markup doing usemap="#map_name". so here's my JavaScript code, and the HTML to follow. Code: var $ = jQuery;
$(document).ready(function(){
$("#viewer").iviewer(
{
src: "images/page11.jpg",
update_on_resize: false,
initCallback: function ()
{
var object = this;
$("#in").click(function(){ object.zoom_by(1);});
$("#out").click(function(){ object.zoom_by(-1);});
$("#fit").click(function(){ object.fit();});
$("#orig").click(function(){ object.set_zoom(100); });
$("#update").click(function(){ object.update_container_info();});
},
onMouseMove: function(object, coords) { },
onStartDrag: function(object, coords) { return false; },
onDrag: function(object, coords) { }
});
$("#viewer2").iviewer(
{
src: "images/page11.jpg",
update_on_resize:false,
initCallBack: function ()
{
document.images[0].useMap = "#map1";
}
});
});
And the 'scaler' Code: function scalecoordimages(elImage, amount){
var elMap = getMap(elImage)
elImage.width *= amount;
elImage.height *= amount;
if (null != elMap){
for (var intLoop = 0; intLoop < elMap.areas.length;
intLoop++) {
var elArea = elMap.areas[intLoop];
var coords = elArea.coords.split(",");
var scaledCoords = "";
for (coords in coords) {
scaledCoords += (coords[coord] * amount) + ",";
}
elArea.coords = scaledCoords;
}
}
}
and now the HTML where this is all delivered. Code: <div class="wrapper">
<div id="viewer2" class="viewer" style="margin: 50px auto;"></div>
</div>
the 'wrapper' is because in Safari the overflow doesn't hold properly and breaks. the Map is just rectangles...it's below > Code: <map name="map1" id="map1">
<area class="hotspot" shape="rect" coords="105, 1110, 371, 1125" href="" onMouseOver="tooltip.show('<ul>Northeast States:<br /><li>Connecticut</li><li>Maine</li> <li>Massachusetts</li><li>New Hampshire</li><li>Rhode Island</li><li>Vermont</li><li>New Jersey</li><li>New York</li><li>Pennsylvania</li></ul>');" onMouseOut="tooltip.hide();" >

My teacher insists that the above code is valid (straight out of our book). He says this because (I'm guessing) it runs okay in Firefox and other browsers. It also throws a ton of error messages in Chrome and makes no logical sense. We define the values of the jackhammer array as literal strings, and then the book instructs us to change the source of the image element on the page to jackhammers[i].src. It then has us change the source of the image element again, correctly at the end of the function. It also has us create a useless variable: "direction" (and I say useless because we never use it, it is just fluff I guess). On a side note, would some of you guys like to check out this animation I created here and let me know what you think. Thanks guys. Hi, I have a programing problem that have been around for ages. I have search on google using several expressions and words and after hours of digging i'm still unable to do it. I would like to get a value from a HTML page hosted remotely with an inconstant value. Then define this value and name as a javascript variable and apply or show in my page. Thanks for all the help P.S. Is there any way to make a domain lookup in javascript? I mean a user enters a domain and the script converts to an ip and shows to the user. If not thanks, probably it can only be done in the server side... 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 ();
