JavaScript - Passing + Character When Passing Parameters Through Url
Dear all,
I'm passing the variables myTitle and myLink to form.php using javascript. This is the way I'm doing it: Code: <a href='form.php?title=" + myTitle +"&link="+myLink+">Click me</a> It's working great but sometimes myTitle and myLink contain the plus character (+). When this happens it's not passed. In the case of the title, it's just a problem of looks but in the case of the link, well, the link won't work without the character. As an example if the title is: Laptop + Accessories What is passed is: Laptop Accessories What can I do to pass also the plus character?? Thanks a lot!! Similar TutorialsCode: function viewDetails(rowid,linkid){
alert("enterining into bundles");
if(linkid=='seobundles')
{
alert("enetering into if ");
document.chwAnnouncementW.action='${contextPath}'+"/dolphin.wss/viewSeobundleW?rowindex="+rowid;
document.chwAnnouncementW.submit();
}
else
{
alert(linkid);
document.chwAnnouncementW.action='${contextPath}'+"/dolphin.wss/viewSeoW?rowindex="+rowid;
document.chwAnnouncementW.submit();
}
}
Actually i am passing linkid="seobundles" as string but its not interpreting and it is always going to else part and not if part. I tried to print link id its teling its of object HTML table type and we are passing the two parameters rowid, linkid from a macro. rowid is working fine as and when we select radio buttion but linkid is not working as an string. IF i pur linkid in single quotes then also its not working I am trying to pass a value using a parameter in html (asp) to a javascript function. When I try to pass a value inside of a variable <INPUT type="submit" value="Next Youth" name=button1 onclick="OnButton1(tst);"> it simply doesn't work (no error msg - just nothing) while if I put a value in the call <INPUT type="submit" value="Next Youth" name=button1 onclick="OnButton1('5393');"> it works fine. The javascript looks like this: function OnButton1(tst) { var pth = "youth_edit3.asp?cIndex=" + tst; document.YouthEdit.action = pth; document.YouthEdit.submit(); // Submit the page } I've set tst = "5393" but it won't work when I try to pass it. Only a literal value of '5393' works. What am I doing wrong? Thank you in advance. Hi, This is a noob question which I've searched all over for but can't find an answer..........which means it probably isn't possible Can I pass a parameter to a javascript function from embedded javascript? I have a function in a separate .js file which accepts a parameter as follows: function initialize(menu){ alert(menu); } When I use the following javascript embedded in my HTML it doesn't work: <SCRIPT LANGUAGE="javascript"> <!-- window.onload = initialize('testMenu'); // --> </SCRIPT> Am I doing something wrong or is this not possible? Thanks for your help I am passing parameters from one page (actually from a frame within a frameset) to another using Javascript. Typically the code is as follows, taking values from a Form. Code: parent.titleFrame.location="frm_right_demo_title.html?MyDateEvent.value='"+ytt+ "'&MyParam_spec.value='"+parent.mainFrame.document.forms.myForm.MyParam_spec.value+"'"; This has worked fine in all browsers including IE, Chrome and Firefox version 2.0.0.2. However, I have now found that it doesn't work with Firefox version 3.6.12. This is because when retrieving the parameters in the new loaded page, the character ' (quote) has been converted to %27 (percent twenty seven). I can write code to replace %27 with the quote character. However, this is lengthy and time-consuming (as I need to have cyclic code as the javascript replace command seems to work only on the first occurrence within a string). Can someone please help me to understand why this is happening and how to overcome it? I have added an event listener to a LI item in the DOM: liNode.addEventListener("mouseover", mouseOn, true); The mouseOn function: function mouseOn(e) { // Test for IE or Firefox var e = (!e)?window.event:e; var yPos; if (e.pageY) { yPos = e.pageY; } else { yPos = e.clientY; } } I would like to pass in another parameter to the mouseOn function in addition to the event that is passed in automatically. Is there a way to do this? Hello, i'm working on a 3 page survey. When hitting next, previous, or submit it passes the values of all the questions to the next page. I've got the whole thing working correcting except for one thing: When the box is "not" checked it passes no value. I'm needing it to have a value of "1" when checked and a value of "0" when not checked, and currently when its not checked and i pass the info it leaves it blank. I'd post the whole code to one of the pages but it's long , so i'll post the snipits of the code. Code: <script type="text/javascript">

The first case that i showed in my code is a radio button, and it passes correctly, i just wanted to show the "format" i was using in a working sense. The 2nd case is an example of the check boxes. Thanks for looking at this, and giving any suggestions you might have! Hi, I have what I assume started as a simple error and then trying to fix it I think I have made things so complicated I've become confused. I have two fields, a drop down list and a text field, when someone clicks on a value in a drop down list (I will show the results eventually but at the moment) I just want the result to echo in my getCategory.php and the same for the text field. Both php pages are currently being called. And at the moment contain $_REQUEST['category'] and $_REQUEST['ProductName'] respectively. Nothing is being echoed. I know the below code is wrong, but the more I try to correct it the worse it gets so I thought I would just leave it as is before I made it worse. Code: <script type="text/javascript">
function loadXMLDoc1(File,ID,Msg){
if (window.XMLHttpRequest) {
xmlhttp=new XMLHttpRequest();
}
else {
try{
xmlhttp=new ActiveXObject("Msxml2.XMLHTTP");

}
}
xmlhttp.onreadystatechange=function(){

document.getElementById(ID).innerHTML=xmlhttp.responseText;
}
}

Hi, I've had problems in the past understanding this, however, after reading this tutorial, I understand. In some languages, like VB6, I notice the "byVal" and the "byRef" is specifically used. In javascript, I don't notice those specifics typed in functions. Is the "default" by value when using in a function to change a parameter? If it is, what is the syntax for using by reference, or is that ever used? My question arises from this notation taken from here: Quote: Note that it is the value that a has at the time that it is passed into the function that gets substituted into the argument and not the value that the original variable has at that point in the processing. It is the values in the parameters that the function uses and not the variables. This is called pass by value . In those languages where you can pass the actual variable into the function instead of just passing its value the method used to do so is called pass by reference . Had we been able to pass the variables into the function by reference rather than by value then the final value in b would have been -16 instead of -14. Here is the example (passing by value): Code: function myfunction(y, z) {
a += y;
b -= z;
}
var a = 0;
var b = 10;
var c = 3;
var d = 4;
var e = 2;
myfunction(c, d);
myfunction(d, e);
myfunction(9, 2);
myfunction(b, a);
Results:
myFunction(c, d); output: 0 + 3 = 3(y), 10 - 4 = 6(z)
myFunction(d, e); output: 3 + 4 = 7(y), 6 - 2 = 4(z)
myFunction(9, 2); output: 7 + 9 = 16(y), 4 - 2 = 2(z)
myFunction(b, a); output: 2 + 16 = 18(y), 2 -16 = -14(z)
Thanks! I've had some help figuring out how to pass a variable through a pop-up window: Code: <script type="text/javascript">
function expo(o) {
var et = document.getElementById(o);
if(et) {
window.open( "exp.php?exportthis="+et.value, "myWindow", "status = 1, height = 300, width = 300, resizable = 0");
}
}
</script>
<form action="" method="post"><input type=hidden value="$file" name="exportthis" ><input type=submit value=Export name= "Exp"onclick="expo('exportthis');" />
</form>
However, my issue is that I have multiple forms. The forms are the same - the variables are different. The code above only works with the first variable returned. Here's an example of the problem. Code: <?PHP
//for example purposes the filename will be labeled as numbers
$i = 1;
while ($i < 5) {
echo "<form action=\"\" method=\"post\"><input type=hidden value=\"$i\" name=\"exportthis\" ><input type=submit value=\"Export\" name= \"Exp\"onclick=\"expo('exportthis');\" /></form>";
}
?>
The above simple PHP script produces 5 simple forms. All of them are identical with the exception of the 'exportthis' or variable that I'm trying to pass through. They are numbered '1' to '5'. If I press the submit button for any of them only the first variable (in this case '1') is passed through. Can someone help me modify the javascript so that the right variable is passed through and not just the first one? Should be simple, but I'm having a complete brain fart. I need to call a function, with a parameter that triggers something relative to that parameter. Pseudo Example Code: function respawn(n) {
case 1
//respawn monster1 code
case 2
//respawn monster 2 code
case 3
//respawn monster 3 code
}
if(killed monster1) {respawn(1)} //respawn(monster1) is what I want to do
if(killed monster2) {respawn(2)}//respawn(monster2) is what I want to do
if(killed monster3) {respawn(3)}//respawn(monster3) is what I want to do
I can... Code: function respawn1(){
//respawn monster1 code
}
function respawn2() {
//respawn monster2 code
}
function respawn3() {
//respawn monster3 code
}
if(killed monster1) {respawn1()}
if(killed monster2) {respawn2()}
if(killed monster3) {respawn2()}
but if I have 10+ monsters I just figured a case structure would be good, or passing the monster to respawn to a single respawn() function......but all the switch examples I could find were based on dateTime which gave case 1-7 based on what day it was, and didn't show how you set your own cases like monster1, monster2, monster3.... I know this is a basic concept...I've read about functions he http://www.quirksmode.org/js/function.html and at w3schools of course but can't figure out how to apply it to my situation Thanks How do I pass an id to a function?? Or is this even possible. Code: <html>

Here is the JS for switching dynamically loading the large image PHP Code: <script language="javascript"> $(document).ready(function() { $('.thumbnail').live("click", function() { $('#mainImage').hide(); $('#atitle').hide(); $('#imageWrap').css('background-image', "url('/images/ajax-loader.gif')"); var i = $('<img />').attr('src',this.href).load(function() { $('#mainImage').attr('src', i.attr('src')); $('#imageWrap').css('background-image', 'none'); $('#mainImage').fadeIn(); $('#atitle').fadeIn(); }); return false; }); }); </script> Here is the link for the thumb PHP Code: // Thumbnail Display echo '<a href="artists/'.$artist.'/'.$imgname.'.jpg" class="thumbnail"><img src="artists/'.$artist.'/previews/'.$imgname.'.jpg" border="0" /></a>'; [/PHP] Link to the large image PHP Code: // Large image display echo '<img src="artists/'.$artist.'/'.$first_image.'.jpg" alt="Main Image" id="mainImage"/>'; Here is the php echo for the title PHP Code: <? echo str_replace('"', '`', $iname); ?> I need to some how pass a php var from the thumb link to the js and have it display dynamically(without reloading) Hope I explained this correctly.. Please advise.. Thanks, Dan Is it possible to pass the id onChange like in this example instead of the value This is part of a large complex script, and I need the id as seperate function Code: <select name='color' onChange='this.form.F1.value=this.form.color.id' > <option value='Green' id='c1'>Green <option value='Red' id='c2'>Red <option value='Blue' id='c3'>Blue </select> <input type="text" name="F1" size="15" value="" onChange="this.value=this.form.color.id"> Hi, I want to pass a javascript function's return value, to an anchor tag's href parameter i.e. <a href> Suppose I have a function called getTrackingCode( ) that contains a value "testSite" Code: <script language = "JavaScript">

{
return "testSite";
}
</script>
Now I want to pass this function's value to anchor's href, I have attempted these: Code: 1. <a href="http://www.helloworld.com/?id=" + getTrackingCode( )> 2. <a href="javascript: document.location= 'http://www.helloworld.com/?id=' + getTrackingCode( );"> So that the resulting URL becomes http://www.helloworld.com/?id=testSite But none of the procedures work. Please help me do it. NOTE: Please note that I can't use the function with document.write to write the whole tag because that would be very hard to manage as I will have to use it in case of text links, image links, hotspots etc. and for each I would have to write a separate function. Furthermore, I don't want the Status bar of the browsers to show something like javascript:location.href (); etc. I want the actual href link to be seen in the Status bar, as if no javascript manupulation is done. In a nutshell, the code should be reusable for the href paramater in anchor tag's href of any element, be it a text link, image link, script link, hotspot or link area and doesn't show javascript function calling in the Status bar of the browser. I've heard that I can do such a thing using ElementbyID etc. but have no idea. Please help me with this, Thanks much! Hello, I'm trying to pass a query from my URL into a <script> using Javascript.

I think this is what I am trying to do, I am pretty new to javascript so I'm not sure... but here is my question... I got this function below. Code: function getProductInfo(id) {
var sku = window.document.InvoiceForm.Item0Sku.value;
alert(sku);
}
when I use the 0 I get the right value back, however whenever I try to pass it the id variable with a value of '0' I can't seem to compose the concatenation correct in order to recieve the correct value. I either recieve errors or the whole window.document.InvoiceForm.Item0Sku.value string back in the alert, what am I doing wrong? I'm trying to pass the following variables.
