JavaScript - Passing A Parameter With The Value Of A Variable
I've been staring at this same problem for over a week now. I've worked around it as best as i can but i think it's time to ask someone else for input.
I'm trying to pass a value thru an ajax parameter.. that's all. it SHOULD be easy in theory. what i want to do is create a jscript variable then pass that variable as the value for a parameter. php then converts that value to something it can use to finish the rest of my code. As i said it's hindering my webpage progress and i would like to get it fixxed soon so any help would be appreciated. Code:
function getSelection()
{
var selection=document.getElementsById("SelectedItem");
var xmlhttp;//create a var for the obj
if (window.XMLHttpRequest)//if requesting an obj...
{
// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else if (window.ActiveXObject)
{
// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
else
{
alert("Your browser does not support XMLHTTP!");
}
xmlhttp.onreadystatechange=function()
{
if(xmlhttp.readyState==4)
{
var text = xmlhttp.responseText;
addNode(text);
}
}
xmlhttp.open("GET","battle_nin.php?selection",true);
xmlhttp.send(null);
}
//the php snippet
$currentjutsu=$_GET[selection];

Hi people, I need help as follows: On the server side I have a php generated session parameter. I need to pass it to javascript on the client side page. I saw on the web the following solution: <script language="JavaScript"> var mySessionVar="<%= Session["MySessionVar"] %>"; </script> I tried it but it did not work. I could not find any explanation of this syntax - will appreciate one. Any suggestions, maybe in another way? Thanks I'm trying to pass the following variables.

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? google is not my friend on this one if I wanted to set a variable with radio buttons to decide whether a function adds or subtracts, I know I can't do this: Code: <body>
<input type="radio" name ="op" onclick="op='-'">count up: <input type="radio" name ="op" onclick="op='+'">
<script type="text/javascript">
var op;
function calc() {
start=start op 1000;
}
</script>
</body>
but is there something I can do, without getting all if/elsey? Hey there, I'll explain what I'm trying to do. I have a back-to-top button on my website that will only appear after the user is 500px down the page. I'd like to be able to change that 500px value to whatever the users window height is. I have a code that retrieves the users window height and will echo it wherever I place the script on my page: Code: <script>
var winW = 800, winH = 600;
if (document.body && document.body.offsetWidth) {
winW = document.body.offsetWidth;
winH = document.body.offsetHeight;
}
if (document.compatMode=='CSS1Compat' &&
document.documentElement &&
document.documentElement.offsetWidth ) {
winW = document.documentElement.offsetWidth;
winH = document.documentElement.offsetHeight;
}
if (window.innerWidth && window.innerHeight) {
winW = window.innerWidth;
winH = window.innerHeight;
}
document.writeln(+winH);
</script>
I'll also post the script for the back-to-top button: Code: <script type="text/javascript" src='<?php bloginfo('template_url'); ?>/js/jquery.min.js'></script><script>
$(document).ready(function(){
// hide #back-top first
$("#back-top").hide();
// fade in #back-top
$(function () {
$(window).scroll(function () {
if ($(this).scrollTop() > 500) {
$('#back-top').fadeIn();
} else {
$('#back-top').fadeOut();
}
});
// scroll body to 0px on click
$('#back-top a').click(function () {
$('body,html').animate({
scrollTop: 0
}, 800);
return false;
});
});
});
</script>
In that first code, it seems like the value +winH is what I need to use. The line document.writeln(+winH); merely prints the value as text on my page. Now in this second piece of code there's two numeric values. The second, 800, is the speed that the page scrolls back to the top. The first value, 500, is the value I want to replace. Can anyone guide me through how I might combine these two scripts to work together? I have a function which is currently called twice on the same page. Part of the function is to apply an onkeyup event to a created element. The problem is that when the function is called twice the first created element calls the onkeyup function of the second element! table_JD.length-1 = 0 for first element table_JD.length-1 = 1 for second element updateSearch_TC_JD(1) is somehow called from first element! Code: newSearchBox.onkeyup = function() {updateSearch_TC_JD(table_JD.length-1)}
Thanks for any help you can provide! Hi, I am having trouble passing the correct id to change the innerHTML. I have a jsp that display people and their address information. There could be several people in the list, so it is in a loop. That part all works good. There is a drop down list with countries in them. Based on the country they select, I want to change some of the text. Here is what I have: Code: <tr>
<td class="datashaded" valign="top"><font size="2"><b>Country:</b></font></td>
<td class="datashaded" valign="top">
<select tabindex="<%=countryTab%>" name="<%=country%>" size=1" onChange="changeText(this.form.<%=country%>, this.form.<%=addressLabel%>, this.form.<%=zipLabel%>);">
<% for (int i =0; i < countryList.size(); i++ ) {
String countryOption = (String)countryList.get(i);
String countryVal = bene.getAddress().getCountry();
String selected = "";
if ( countryOption.equalsIgnoreCase( countryVal ) )
selected = "selected";
%>
<option value="<%=countryOption %>" <%=selected%> ><%=countryOption%></option>
<% } %>
</select>
</td>
</tr>
<tr>
<td class="datashaded"><div id="addr1"><font size=2><b id="<%=addressLabel%>">Address:</b></font></div></td>
<td class="datashaded">
<input size=20 maxlength="50" tabindex="<%=add1Tab%>" name="<%=address1%>" value="<%=address1Value%>" </td>
</tr>
Everytime through the loop, addressLabel has an index added to it so it is unique - so I can refer to each person separately. Here is the js function: Code:
function changeText(sel, txtField1, txtField2)
{
var selectedValue = sel[sel.selectedIndex].value;
if ( selectedValue == "<%=IParticipantConstants.BENEFICIARY_COUNTRY %>")
{
document.getElementById(txtField1).innerHTML = 'Address:';
document.getElementById(txtField2).innerHTML = 'Zip:';
}
else
{
document.getElementById(txtField1).innerHTML = 'Street or P.O. Box';
document.getElementById((txtField2).innerHTML = 'Postal Code:';
}
}
When I hardcoded the id= value, not matter which group I changed the country on, only the first one was changing, so I knew I needed unique ids for each group. There is more to the table, but this is the good part. When the onChange fires now, Nothing at all happens. Can anyone see the problem?? Thanks for looking! Hi, I'm having one javascript function which will return the variable and I need to pass that variable to command button action.Please find the below code and let me know how I can achieve this. <script> function addEntry(entries) { var uploadedEntry = entries[0].entryId; alert("Uploaded Entry Details::::" + uploadedEntry ); } </script> <h:commandButton tabindex="1" image="../img/submit.gif" action="#{portfolioListing.uploadMediaEntry(uploadedEntry)}" Thanks, Anil Hello Can i pass php Variable into javascript function like this example.

When the user clicks a button, it turns that <span> into a textarea that the user can type a new name in, press enter, and then the span contains the text the user input. Sort of like when you rename a file in Windows Explorer. Anyway, the code is something like this, and I'm wondering if I can use 'area_el' in this way... right now it's giving me the error that area_el is undefined, even though I define it in the function that contains the Event declaration. The first part is the Dom stuff to make it all work. It's not stuff I need to mess with, but I'm putting it here in case it's useful. Code: var Dom = {
get: function(el)
{
if (typeof el === 'string')
return document.getElementById(el);
else
return el;
},
add: function(el, dest)
{
var el = this.get(el);
var dest = this.get(dest);
dest.appendChild(el);
},
remove: function(el)
{
var el = this.get(el);
if(el.parentNode != null)
el.parentNode.removeChild(el);
}
};
var Event = {
add: function()
{
if (window.addEventListener)
{
return function(el, type, fn)
{
Dom.get(el).addEventListener(type, fn, false);
};
}
else if (window.attachEvent)
{
return function(el, type, fn)
{
var f = function()
{
fn.call(Dom.get(el), window.event);
};
Dom.get(el).attachEvent('on' + type, f);
};
}
}()
};
The following code defines what happens when the user clicks submit to create a polygon. I also have some variables: Code: var created_area_array = Array();
var createdarea_index = 0;
var number_of_areas_saved=0;
var currently_renaming=false;
Event.add(window, 'load', function()
{
Event.add('SubmitArea', 'click', function()
{
if(polyPoints.length>0)
add_created_area();
});
});
Finally, where the issue is. I define area_el in the function below, and further down I want to pass it to a function within the "rename" click event, but I get an error that area_el is undefined. Code: function add_created_area()
{
number_of_areas_saved++;
var area_el = document.createElement('span');
var area_el_remove = document.createElement('span');
var area_el_rename = document.createElement('span');
var new_entry = polyPoints;
var new_entry_array_index = "Area" + (createdarea_index);
var new_entry_array_name = "Area #" + (createdarea_index+1);
area_el.innerHTML = '<span class=\"address-text\">' + new_entry_array_name + '</span><br>';

created_area_array[new_entry_array_index] = new_entry;
createdarea_index++;
Dom.add(area_el_remove, 'CreatedAreas');
Dom.add(area_el_rename, 'CreatedAreas');
Dom.add(area_el, 'CreatedAreas');
Event.add(area_el, 'click', function(e)
{
if(!currently_renaming)
{
polyPoints = [];
var thePolyPoints = (created_area_array[new_entry_array_index]).toString();
alert(thePolyPoints);

The enter_rename(area_el, event) function that isn't passing in my variable. Code: function enter_rename(area_el, event)
{

Making area_el global does not clear the span elements when I click my "createdarea_clear" button, however when it's local, the function works as expected. I'm more of an actionscript person but got roped into an html/javascript job. What I need to do, and it shouldn't be that difficult is this: page1.html - there is a yellow button and a red button - if the user clicks on the yellow button I want to set a cookie with the value "yel" then load the next page - if they click the red button set that cookie with the value "red" page2.html - 'onload' i want to read that cookie and load up the main image to match, something like this maybe?... document.mainimage.src='img/main_' + variable + '.png' so that the path would be for example 'img/main_red.png' Any help please? Preferably javascript only and as simple as possible. If you think this would be easier sending that variable in the URL instead of as a cookie please explain. I'm having a very hard time searching for tutorials that are any good and that do exactly this kind of thing. 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. I have the following code, where I am inputting a word and on clicking the button , i am setting the value of the text box in div class="twit" which is hidden. now I have to access the value of this hidden text box (name=q) using php.Say I want to print using php .How do I do this ? Code:
<html
<head>
<title></title>
<link rel="stylesheet" href="search.css" type="text/css" media="screen" />
<script type = "text/javascript">
function gettweet()
{
document.getElementById("src").value= document.getElementById("searchbox").value;
}
</script>
</head>
<BODY>
<form align="center">
<div id="top">
<h3>Search </h3>
<input type ="text" name="q1" id = "searchbox"\>
<input type ="button" value="ClickMe!" id = "b1" onclick="gettweet();"\>
</div>
<div id= "twit">
<input type ="text" name="q" id = "src"\>
<?php
?>
</div>
</form>
</BODY>
</HTML>
I need to get this script to work, I only included what im having the problem with. I am Using jQuery Library. Here is how this should work: .btnRoof div is clicked the parent id is retrieved as var pid a function called roof is called which simply changes a css background to "color" the function perform is called to get the "color1[0]" from the array. My Problem: perform() returns the word color1, color10, color1[0], or c. instead of images/cp-roof-blue.png as listed in the array. Code: $(document).ready(function() {
var color1=new Array();
color1[0]="images/cp-roof-blue.png";
color1[1]="images/cp-panel-blue.png";
color1[2]="images/cp-trim-blue.png";
function perform(name, x) {
alert(name[x]);
//alert([name][x]);
//alert(name+'['+x+']');
//alert(color1[0]); // correct
return name[x];
}
function Roof(color) {
$("#colorPicker .roof").css("background", "url("+color+")");
}
$('.btnRoof').click(function() {
var pid = $(this).parent().parent().attr("id");
Roof(perform(pid, 0));
});
});
I tried to clarify as much as possible, please let me know if I need explain further. Thanks. Every time i click on one of the said elements, it puts "undefined" into the textbox each time i click on an element. it seems to me that the Key_Table[x] is not getting passed correctly. How do i make sure that this is getting passed correctly? Here's my Code: Code: <script type='text/javascript'>
// Startup Script
if (document.addEventListener) {
document.addEventListener("DOMContentLoaded", LoadEventListeners, false);
}
function LoadEventListeners()
{
var Key_Table = ["q", "w", "e", "r", "t", "y", "u", "i", "o", "p"];
// Create event Listeners for the alphabetic keys
for(var x = 0; x < Key_Table.length; x++)
{
Key_Table[x] = document.getElementById(Key_Table[x]);
Key_Table[x].addEventListener("click",
function(){
InsertChar(Key_Table[x]);
},
false);
}
}
function InsertChar(Char)
{
alert("Char is:" + Char);
// Textbox data
document.getElementById('TextData').value = document.getElementById('TextData').value + Char;
}
</script>
I have a signup form on a site that does a check on submission of fields to see if they populated and error box if not changes focus to missing field and highlights field name in red. I wanted to improve on its effectiveness as it only checks 2 fields atm and I wanted it to check some dynamic fields as well the fields are associative arrays generated via php as follows:- Code: echo "<select name='nfield[$t]'>\n";
for ($i = 0; $i<count($value2); $i++) {
echo "<option value=\"".trim($value2[$i])."\">".trim($value2[$i])."</option>\n";
}
echo "</select>";
the javascript is as follows:- Code: function checkForm() { //This is the name of the function
if (Form1.password.value == "") {
alert("Please enter a Password.");
Form1.password.focus( );
document.getElementById('password').style.color="red";
return false;
}
The field is displayed via php as follows:- echo "<tr><td align='center' id='password'>Password:</td><td><input type='password' name='password' size='10'></td></tr>\n"; So i thought ah easy, i will just add the following checking javascript to check each of the associative arrays as they never change Code: if (Form1.nfield[1].value == "") {
alert("Please choose an option for option1");
Form1.nfield["1"].focus( ); //This focuses the cursor on the problem field
document.getElementById('nfield[1]').style.color="red";
return false; //This prevents the form from being submitted
}
if (Form1.nfield[2].value == "") {
alert("Please choose an option for option2");
Form1.nfield[2].focus( ); //This focuses the cursor on the problem field
document.getElementById('nfield[2]').style.color="red";
return false; //This prevents the form from being submitted
}
if (Form1.nfield[3].value == "") {
alert("Please choose an option for option3");
Form1.nfield[3].focus( ); //This focuses the cursor on the problem field
document.getElementById('nfield[3]').style.color="red";
return false; //This prevents the form from being submitted
}
but this doesn't work, i think it doesn't recognise the nfield[1] syntax, can a javascript guru point me in the right direction ? I also wanted to enhance the form somewhat as atm it only displays one error popup at a time, so if the user has missed out a few fields they will get an initial popup, try and submit again and then get the second popup for the other missing field. Can my code be modified to show a list of the missing fields and highlight all the titles in red (and if possible change the background colour of the input boxes or border the input fields in red etc)? I'm trying to make it so when you click a cell in a table it runs a function based on the value within that cell. With the current code, no matter what cell is clicked, the alert box displays the same number, which is the last number in my array. The variable, princ, is just being overwritten rather than writing code to each the cell with the proper value. Help is appreciated. Thanks. Code: for(i=0;i<=3;i++){
document.writeln('<tr>');
document.writeln('<th>'+(periodArray[i])+'</th>');
for(j=0;j<=2;j++){
princ = principleArray[j][i];
document.writeln('<td onclick="(calculateInterest(princ,1,1))">$'+principleArray[j][i]+'</td>');
}
