JavaScript - How To Enable A Submit Button On Hidden Field Population
I thought this would have been fairly simple but it appears the onchange event isn't triggered when a hidden field is populated by other javascript without user input.
I have a simple search box and autocomplete/suggestion ajax thingie going on. What I want to do is have my "Go" submit button disbled until AFTER a user has populated the hidden field "cid". A user populates this field automatically when they click on a suggested option from the ajax autocomplete doofer. Here's what I've tried at the moment but failed on. Code: <form action="index.php" method="GET" name="qsform" id="qsform">
<input type="hidden" name="p" id="p" value="compdetails" style="border:1px solid #000000;" />
<input type="text" name="quicksearch" id="quicksearch" value="Find Company" style="border:1px solid #000000;" onFocus="clearText(this)" onBlur="clearText(this)" />
<input type="hidden" name="cid" id="cid" value="" style="border:1px solid #000000;" />
<input type="submit" name="go" id="go" value="Go" disabled="true" onmouseover="if (document.qsform.cid.value!='') { document.qsform.go.disabled=false; }" />
</form>

Hello Having problems with the following...a client needs me to replicate this contact page: http://www.ravenrow.org/contact/ In particular he wants the subscribe/unsubscribe to appear only when one enters text into the text field (as it does here). I have recently changed from using tables to div tags but this was the first website where I started to experiment with divs. Unfortunately therefore it is a mixture of tables and divs. But here is my page: http://www.rowingpresents.com/contact.html Can someone tell me what I need in my code to have to subscribe/unsubscribe appear and disappear as it does at ravenrow.org. Many thanks S Dear All I have done some coding in javascript . Where i am generating the textbox field and checkbox dynamicaly . That is as per condition if there is one record match as per condition then that many text field will be generated So just to give a example , which is not dynamical What i want to do is first the text field are disable and when the checkbox is checked then the text box should be enable For 1 record the logic is working proper , but if there are more then 1 record then it does not work Can you'll please help <?php session_start();?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> <link rel="stylesheet" href="../locationpropertydesirecom/css/adcss1.css" type="text/css" media="screen" /> <script language="JavaScript"> function enable_text(status) { status=!status; var e=document.getElementsByTagName("tr"); for(var i=0;i<e.length;i++) { e[i].disabled = status; } } </script> </head> <body> <table> <tr> <td><input type="text" id="aa" name="a" disabled="disabled"/></td> <td><input type="text" id="aa" name="b" disabled="disabled" /></td> <td><input type="checkbox" name="aa" value="check" onclick="enable_text(this.checked)" /> </tr> <tr> <td><input type="text" name="a" disabled="disabled"/></td> <td><input type="text" name="b" disabled="disabled" /></td> <td><input type="checkbox" name="aa" value="check" onclick="enable_text(this.checked)" /> </tr> </table> Thanks , regards Jim Within my project, using PHP/HTML/Javascript, I am trying to set up a page where a corresponding submit button is enabled when a given checkbox is checked. What complicates my attempt is that the checkboxes and submit buttons are in the form of arrays. Here is a snippet of my code: Code: <form name="myform4" id="list_apps" method="post">
<?php
for ($i=0; $i<$num_rows;$i++)
{
?>
<p>
<input type="checkbox" name="app[]" id="app[]" onclick="enable_perm()">
<input name="set_perm[]" type="submit" id="set_perm[]" value="Set Permissions">
</p>
<?php
}
</form>
Here is my attempt at using Javascript to disable the first submit button after clicking any check box: Code:
function enable_perm()
{
document.myform4.set_perm[0].disabled = true;
}
What am I missing here, or, how do I enable/disable submit buttons that are part of an array? How can I make this code disable the submit button once it has been pressed, then if the user hits back or GOES back, it will re-enable it again? Code: <SCRIPT LANGUAGE="JavaScript" TYPE="text/JavaScript">
function formControl(submitted)
{
if(submitted=="1")
{
commentForm.Submit.disabled=true
alert("Thanks for your comments!")
}
}
</SCRIPT>
Thanks! ShadowIce~ I have a telephone input on my form. It is an optional input for users. The prompt begins with the user having to select a phone type from a select menu, and then continue to the text fields to enter the digits. I would like to have the text fields disabled unless any of the types of phone are selected, but not if a type isn't selected. Here's my HTML code so far: Code: <select name="phoneType1"> <option value="" selected="selected">Type...</option> <option value="Home">Home</option> <option value="Work">Office</option> <option value="Cell">Cell</option> </select> (<input type="text" id="phAreaCode1" name="phAreaCode1" size="2" maxlength="3" onkeyup="moveOnMax(this,'phPrefix1')"/>) - <input type="text" id="phPrefix1" name="phPrefix1" size="2" maxlength="3" onkeyup="moveOnMax(this,'phLine#1')"/> - <input type="text" id="phLine#1" name="phLine#1" size="5" maxlength="4"/> ext.<input type="text" name="phExtension1" size="4" maxlength="4"/> I know that all I need to do to disable the text fields is to type in "disabled" before the name of the field. But, I don't know how to enable it when "Home," "Office," or "Cell" is selected. Thanks for any help. I am trying to make it so if a PHP session entity exists, then JavaScript will enable a button. I am having trouble getting this to work and wondering if anyone knows what I am doing wrong? Code: function purchaseEnable() {
if ($_SESSION['order']['paymentmethod']) {
document.getElementById("purchase").disabled = false;
}
}
Code: <INPUT disabled id="purchase" type="submit" value="PURCHASE"> Hi I have a form where I want to force users to accept terms and conditions before they can move on to the next page (submit form). Code: <input tabindex="2" name="agreement" id="agreement" type="checkbox" value="N" onchange="checkAgreement()" />
<label class="checking" for="agreement">I accept the <a tabindex="1" href="?page_id=292" title="read this before you continue" class="popmeup">terms and conditions</a>.</label>
<!-- the button to be enabled -->
<input tabindex="3" type="button" name="confirmer" value="Confirm" onclick="confirmOrder()" disabled="disabled" />
and the JS that works fine in Firefox. IE enables the button, but it still "looks" disabled, hence it is unlikely that anyone clicks it. Code: function checkAgreement()
{
if(document.order_form.agreement.checked)
{
document.order_form.confirmer.disabled = false;
//document.order_form.submit.disabled = false;
document.order_form.agreement0.value = "Y";
//for testing
//document.order_form.confirmer.value = document.order_form.agreement0.value;
}
else
{ document.order_form.confirmer.disabled = true;
//document.order_form.submit.disabled = true;
document.order_form.agreement0.value = "N";
//document.order_form.confirmer.value = document.order_form.agreement0.value;
}
}

I'm having trouble programming a radio button to enable a group of checkbox options. I want the group to be disabled unless the radio is selected. Can I use: Code: document.getElementById("").disabled=true/false
for a <div> section? Here's what I have so far. function: Code: function disableSection() {
if (document.forms.radio.checked)
document.getElementById("optionalinfo").disabled = false;
else
document.getELementById("optionalinfo").disabled = true;
}
HTML: Code: <input type="radio" name="additionalinfo" value="yes"/>Yes! Please sign me up for the following items:<br/> <div><blockquote><input id="optionalinfo" type="checkbox" name="additional" value="newsletter"/> I wish to receive <font color="ff69b4"><i>AMT</i></font>'s monthly E-Zine, <b>"Glorious Morning Muffins"</b>.</br> <input id="optionalinfo" type="checkbox" name="additional" value="Updates"/> I wish to receive <font color="ff69b4"><i>AMT</i></font> updates.</br> <input id="optionalinfo" type="checkbox" name="additional" value="future"/> Keep me posted about future offerings at <font color="ff69b4"><i>AMT</i></font>.<br/> <input id="optionalinfo" type="checkbox" name="additional" value="userRegister"/>I need to register to log in</blockquote></div> In addition to this, I would like the section to fade when disabled. Thanks for any help... again! I've got the following 2 fields in my form: <input type="file" name="filename" id="filename" value="filename"> <input type="submit" name="submit" value="Upload Image" /> Now I want to hide both of them as soon as the submit button is pressed. Problem is that I'm a javascript noob and I can't find it with google :S Can someone help me? I've been handed an html document that contains a centered, scrollable <iframe> element with a static height and width. This iframe element displays a simple html document that houses the 'terms of service' text. Their goal is to have it to where the <a href> link at the bottom that is shown to the user as 'next' is disabled until the user scrolls to the bottom of the terms of agreement box. The clickable link could be a button, image or text (no preference). They have to have it this way for legal reasons and radio buttons or checkboxes will not suffice unfortunately. Question: What is the best way to go about doing this that seems to be cross-browser friendly (especially IE7). I offer $10 via paypal for well commented method/script. Hey Guys, I have the following hidden field within a form: Code: <input type="hidden" name="test12" value="test12" /> I also have the following function which does something if that field exists: Code: if(document.formName.test12.value == "thisdata")
{
//do something
}
The problem I'm having is that if the hidden field doesn't display (which based on conditional logic, sometimes happens), a JS error is thrown on the page. What is the best way to carry out this check effectively without throwing an error if the field does not exist? Thanks in advance. I have a hidden field whose value is a text string, "xyz". I want to write the value to the page so that the user can see it but not edit it. Can't I just use document.write(form.field.value)? Why isn't it working?
I have a simple script connect to a radio button. Based on which option, the matching div appears with a text box - and one with a radio button. If they change their mind and click another radio button, it'll switch to the new div, but keep the content in the old. How do I clear that out? I looked for a snippet, but they're all for clearing default text in a field when you click it. I want something a little different. Here's what I'm using: Code: <script>
$(document).ready(function() {
$("div.desc").hide();
$("input[name$='hear']").click(function() {
var test = $(this).val();
$("div.desc").hide();
$("#" + test).show();
});
});
</script>
<input type="radio" name="hear" value="dcranch"> DC Ranch Community <br />
<input type="radio" name="hear" value="friend"> From a friend <br />
<div style="display: none;" id="dcranch" class="desc"> <input type="checkbox" value="Yes" name="resident" /> If so, are you a DC Ranch resident? )</div><br />
<div style="display: none;" id="friend" class="desc"> Name? <input type="text" name="how1" /></div><br />

I have modified a free JS function from he http://www.tangorangers.com/examples...post/index.php To dynamically add text fields to the form. My work-in-progress version is he http://jimpix.co.uk/junk/test/6.html On the form, I have a hidden text field: Code: <input type="hidden" name="hiddenCount" value="" /> What I'd like to do is to increment the hiddenCount each time the "Add" fields button is clicked. This is the button: <input id="add_contact()" onclick="add_contact()" value="Add" type="button"> And this is the JS function: Code: var contact_counter = 0;
function add_contact()
{
if (contact_counter < 9)
{
contact_counter++;
var newFields = document.getElementById('add_contact').cloneNode(true);
newFields.id = 'contact';
newFields.style.display = 'block';
var newField = newFields.childNodes;
for (var i=0;i<newField.length;i++) {
var theName = newField[i].name
if (theName)
newField[i].name = theName + contact_counter;
}
var insertHere = document.getElementById('add_contact');
insertHere.parentNode.insertBefore(newFields,insertHere);
}
}
I'm new to JS. I could just about edit the JS function to slightly modify it from the tangorangers version (I only changed it v. slightly). To somehow increment the value in the hidden field each time the button is pressed is beyond me though! Any advice much appreciated. Thanks |
