JavaScript - Passing A Javascript Variable To Hidden Input
Hi all,
I'm having some trouble with the this... I have a PHP based calendar where the cells will change color depending on the number of clicks.. this all works fine, but is pointless if I can't send the outcome along in an email. I can do this with PHP but first need to get the values into a hidden field. This is what I have: Code: <script type="text/javascript">
function countClicks (obj){
if (!obj.count) {
obj.count = 0;
}
obj.count++;
if (obj.count > 4) {obj.count = 1};
if(obj.count == 1){
obj.style.color='#FFFFFF';
obj.style.backgroundColor='#66CC33';
obj.parentNode.style.backgroundColor='#66CC33';
document.getElementById("availability").value='Available';
}
if (obj.count == 2){
obj.style.color='#FFFFFF';
obj.style.backgroundColor='#FF0000';
obj.parentNode.style.backgroundColor='#FF0000';
document.getElementById("availability").value='Not Available';
}
if (obj.count == 3){
obj.style.color='#FFFFFF';
obj.style.backgroundColor='#FFCC33';
obj.parentNode.style.backgroundColor='#FFCC33';
document.getElementById("availability").value='Working';
}
if (obj.count == 4){
obj.style.color='#000000';
obj.style.backgroundColor='#FFFFFF';
obj.parentNode.style.backgroundColor='#FFFFFF';
document.getElementById("availability").value='Not Set';
}
}
</script>
and... Code: echo "<input type=\"hidden\" name=\"availability\" id=\"availability\" value=\"\">"; All I'm trying to do is populate value with either 'available', 'not available', 'working' or 'not set'... however, it is worth noting that each cell may have a different value, e.g. 1 cell might be working while the other is not available... so i need to pass the values of all the cells. Can anyone help me out here. Many thanks, Greens85 Similar Tutorialshi guyz i do have a problem in passing javascript variable to <input type=hidden value=""> here's my code: <?php while ($row = mysql_fetch_array($result)) { ?> <script type="text/javascript"> function viewcodec(){ var randomValueCodec = randomString(5, 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789'); document.getElementById('commentMarkCodeCompCodec-'+<?php echo $row['p_id'];?>).innerHTML = randomValueCodec; document.getElementById('commentMarkCodeComp-'+<?php echo $row['p_id'];?>).innerHTML = randomValueCodec; } </script> <form action="" method="post" name="postsForms"> <div class="commentBox" align="right" id="commentBox-<?php echo $row['p_id'];?>" <?php echo (($comment_num_row) ?

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. Afternoon All, I have managed to secure some JavaScript code from another site that allows me to access values from within my Google Analytics cookie: <!-- begin Referer Check --> <script type="text/javascript"> var gaJsHost = (("https:" == document.location.protocol) ?

I have tried to pass just the source var from within the <script> tags. document.forms["cforms2"].elements["cf2_field_1"].value = source; I have commented out part of original code that I did not think I needed. Any help that can be offered I would be grateful, ultimately I would like to be able to pass all these values to hidden fields. Thanks Paul Brown I really thought this would work, a user goes to a page, selects a value from a select box then clicks a link to run a report using that hidden variable as a parameter. I am attempting to place the value in the URL to pass it. I'm sure the javascript is working, and maybe it's the HTML I've messed up - not sure. Here is the javascript (the alert does return the correct value): Code: function OnChangeDay() {
//assign the day id to the hidden variable $day
x=eval(document.getElementById("day_loc_id_select").value)
if(x) {
document.getElementById("test_day_id").value=x;
} else {
document.getElementById("test_day_id").value=0;
}
// test
alert(document.getElementById("test_day_id").value)
}
Here is the calling HTML: Code: <input type="hidden" name="test_day" id="test_day_id" value="">
<select name="day_loc_id" id="day_loc_id_select"
onchange="OnChangeDay()">
<option></option>
<?= form_options($day_loc_options) ?>
</select>
And here is the HTML that should send the value, but I get day= (nothing) Code: <a href='/depts/edoptions/excel_extract.php?ex=2&day=<? echo $test_day ?>'>SLIP Data to Excel</a> Can anyone point out where I've messed up? Thanks Hi, I wanted to know if there is way in Javascript to send a hidden variable to an external URL without actually submitting to the URL? Code below is what I intend to do. I want to use an image to do an onClick event and send the name to an external URL without actually doing a submit. Code: <td width="25"> </td> <input type="image" src="images/btn_Activate.gif" onClick="window.location.href='www.abc.com'"> <input type="hidden" name="name" value="<% = name %>"> </td> Thanks. Jeeten. Hello Can i pass php Variable into javascript function like this example. PHP Code: <script type="text/javascript"> <!-- function confirmation() { var answer = confirm("are u sure?") if (answer){ window.location = "user.php?action=statusd&uid=".$row['id'].""; } else{ alert("Canceled") } } //--> </script> This ".$row['id']." will be an user id ... link PHP Code: <a href='#' onclick='confirmation(); return false;'>Go</font></a> 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 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 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"\>

<?php
?>

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>');
}
document.writeln('</tr>');
}
function calculateInterest(principle,rate,period){
totalInterest = principle * rate * period;
totalLoanCost = principle + totalInterest;
alert('Total Interest: '+totalInterest+'\n'+'Total Loan Cost: '+totalLoanCost);
}
I have two versions of this document. The first version uses only JavaScript and the standard PROMPT(). It works very well, but I would like to insert the name prompt into the page using the input command. For some reason the variable loaded in the HTML statement doesn't get passed to the JavaScript. Any ideas would be appreciated! This is only a small test page.

Thanks for the help 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 few sites said to (in the js file) put the varible in <%= %> these tags but thats not doing any good. Is there some other part needed to this I'm missing. The javascript I'm using is in a file I included in my VS project.
On my main page, I have a list of item ID's which are assigned variables, the list is concatenated and so the variables are always different. So another thing that gets concatenated is a link, which uses javascript/jquery to open a popout modal window which is another php file called sharepost.php. I want to be able to transfer the php variables from the main page to append them on the end of the sharepost.php URL so I can use $_GET to grab them for use. Here's what I have... not working, but I figured I'd give it a try. Code: <?php
//use mysql to loop through some variables
$post_id = $setvalue;
$member_id = $anothersetvalue;
$list .= '
<div>
' . $post_id . '
</div>
<div>
' . $member_id . '
</div>
<div>
<a href="#" class="button" onClick="openup(); return false">Share This Post</a>
</div>
$the_link = " http://sharepost.php?post_id=' . $post_id . '&member_id=' . $member_id . ' ";
';
?>
<HTML>
<head>
<script>
// Displays an external page using an iframe
function openup(){
var src = "<?php echo $the_link;?>";
$.modal('<iframe src="' + src + '" height="450" width="830" style="border:0">', {
closeHTML:"",
containerCss:{
height:150,
padding:0,
width:350
},
overlayClose:true,
});
}
</script>
</head>
<body>
<?php echo $list;?>

Hi all, I am new to JS and usually learn by studying code posted online and modify it to have it do what I need. Recently, I used a totaling plugin for an online ordering form which does the below: item1 qty(user input text) * preset price = total price item2 qty(user input text) * preset price = total price item3 qty(user input text) * preset price = total price -------------------------------------------------------- grand total -------------------------------------------------------- The JS code which passes the grandTotal variable is as below: Code: function ($this){
// sum the total of the $("[id^=total_item]") selector
var sum = $this.sum();
$("#grandTotal").text(
// round the results to 2 digits
"₹" + sum.toFixed(2)
);
}
The problem I have is the above grandTotal displays the final value when put into a table like below: Code: <td align="right" id="grandTotal"></td> But I am unable to make it work by passing it into a variable within the form fields. I would like to do something like this: Code: <input type="text" name="grandTotal" id="grandTotal" readonly="readonly" /> Can somebody please help me fix this? Any help will be greatly appreciated. Thank you. Hi! I am quite new to the world of JavaScript as I have done basic corse for it... and I have learnt that best way to understand it is to play around with it... but now I am stuck with on of the problem!! Problem: How can we assign text box input values by user to a variable and display that variable back on another element of the same HTML document(dynamically)... Conditions: The value has to be stored as a JavaScript variable only. No server-side script is to be used and has to be done locally. Please help! i am getting a problem while passing parameter to another 'jsp' through hidden variables.I am getting null while requesting the parameter in 'mywindow.jsp' my code goes like this <form name="name" enctype="multipart/form-data"> <input type="hidden" name="flag" id="flag" value=""/> ........ </form> setting its value in javascript.. like this.. <script type="text/javascript"> function openNewWindow(){ var flag1="1"; document.getElementById("flag").value=flag1; document.tstForm.action = "Mywindow3.jsp"; document.tstForm.method = "POST"; document.tstForm.submit(); } </script> in mywindow.jsp:: <% String strFlag = request.getParameter("flag"); out.println("strFlag:"+strFlag); %> i am getting "null" as value of strFlag.I need to use enctype as "multipart/form-data" to submit form. After searching the web most of the day, nothing has resolved this issue: Code: <!-- ALERT IS NEVER HIT -->
<html>
<input type="hidden" id="info" name="info" value="testInformation"/>
<script type="text/javascript">
var me = document.getElementById('info').value;
alert(me);
</script>
</html>
Code: <!-- ALERT SAYS "null" -->
<html>
<input type="hidden" id="info" name="info" value="testInformation"/>
<script type="text/javascript">
var me = document.getElementById('info');
alert(me);
</script>
</html>
Code: <!-- WORKS GREAT, BUT I NEED THE INPUT FIELD HIDDEN -->
<html>
<input type="text" id="info" name="info" value="testInformation"/>
<script type="text/javascript">
var me = document.getElementById('info').value;
alert(me);
</script>
</html>
Any idea how I can keep the input value "hidden" and have javascript still see the value? And yes, I've even tried using the "defer" method. |
