JavaScript - Js Checkboxes Checker Adaptation For Php
Hi,
I have good script Code: <script type="text/javascript">
function chkcontrol(j) {
var total=0;
for(var i=0; i < document.form1.opt.length; i++){
if(document.form1.opt[i].checked){
total =total +1;}
if(total > 11){
alert("No more than 11 please")
document.form1.opt[j].checked = false ;
return false;
}
}
}
</script>
But this script works only If I have: <input type="checkbox" name="opt" value="1" onclick='chkcontrol(1)'>Opt 1 <input type="checkbox" name="opt" value="2" onclick='chkcontrol(2)'>Opt 2 I need to proces this form with PHP so, when I change opt to opt[] (<input type="checkbox" name="opt[]"..) script doesnt work anymore. Couldnt find any script for it, so help me if you can. Thank you Similar TutorialsI badly need a Javascript syntax checker for my Javascript. Any suggestionss will be gratefully received. Frank I have used this script successfully: http://www.javascriptkit.com/script/...2/refer2.shtml However, is there a way to block the following work-around (example only): http://www.their-url.com/redir.php?u...ww.my-url.com/ The redir.php makes it possible to get past the script. I have a js counter which keeps track of how many chars are in a field on an asp form. When the user clicks a button further down in the form, the form generates more fields. This also causes the js counter to reset to its original value, as the page is 'reloading' in a way. How can I check this value and keep it the same when the user clicks this button? I am including the code I have, if anyone has any ideas/suggestions thanks javascript Code: <asp:Content ID="Content1" ContentPlaceHolderID="headContent" runat="server">
<script type="text/javascript">
//limit of chars
var lim = 128;
function count(a) {
//difference count
var dif = lim - a.value.length;
while (dif < 0) {
a.value = a.value.replace(/.$/, '')
dif = lim - a.value.length;
}
//display difference count
document.getElementById('myspan').firstChild.data = dif;
}
</script>
counter in code Code: <asp:TextBox ID="txtHeadline" runat="server" Width="600px" MaxLength="128"
CssClass="VariableText" onkeyup="count(this)"></asp:TextBox>
</td>
<td valign="middle" width="160px">
<asp:Label ID="Label14" runat="server" Font-Bold="True" Font-Names="Tahoma" Font-Size="8pt"
Text="Characters Remaining: " Width="130px" CssClass="LABEL"
Height="16px"></asp:Label>
<span id="myspan" Font-Names="Tahoma" Font-Size="8pt">128</span>
button Code: <asp:Button ID="btnInitializeTemplate" runat="server" OnClick="btnInitializeTemplate_Click"
Text="Initialize Template" CssClass="LABEL" />
i have tried Code: <asp:Button ID="btnInitializeTemplate" runat="server" OnClientClick="return count(document.getElementById('txtHeadline'));" OnClick="btnInitializeTemplate_Click"
Text="Initialize Template" CssClass="LABEL" />
it compiles but the value remains reset. any advice on what im doing wrong? hi i want to create one java code that do this : 1-one counter is counting 20 to 0. 2-if counter 0 then choose random string between "click one" , "click two" , "click three" and show it. 3-in other table we have three button that name`s are "one" , "two" ,"three". 4-for continue page user must click true button,if user click false button alert "wrong". thx Visitors enter information in textarea's and form fields and I wish to allow them to have this spell checked before submitting. What methods are open to me to do this. Hello, I'm building a simple custom dropdown menu for a web-site so that I can control look and feel as well as the behavior of an iframe. I've set it up so that when the user clicks on any of the menu's active components, an "if" sequence in the clickHandler() function is activated that gets the element's class. If the event occurred on a dropdown option, the event-target id is checked, and the appropriate function is called. At least this is how it's supposed to work. All of the drop-down options have been assigned the "dmo" class. When I test the menu and click on other elements, it works fine. But when I click the "dmo" drop-down options, nothing happens. Firebug and IE Explorer Developer Tools both show no errors, but on clicking a dropdown option, the correlate code doesn't run at all, and after hours of head-banging, I have no idea why. I need help on this one. Here's the code. Code:

My form generates 1 to n records which contains check boxes. Based on some condition if I click a check box it has to check & disable some other check boxes automatically. I did it. But, at the same time if I un-check I have to un-check all the check boxes which were checked. Please let me know. Thanks a lot.
All, I have the following code which validates a form has at least one checkbox checked before it submits it. However I want to make sure that there aren't more then 25 checked on the page. How can I do this? Code: function validate(field)
{
for (var i = 0; i < field.length; i++){
if(field[i].checked){ // if a field is checked form is submitted
return true;
}
}
alert("You need to have a check box selected to submit the form!");
return false; // if no fields are checked form not submitted
}
Thanks in advance! Hi all. I have the following problem that I require a pointer with. I have a php variable named "$seatid" This could contain 1 or many entries. I have a page full of checkboxes named A1-8, B1-8, C1-8 etc to P1-8 I want a way of greying out the checkboxes on the page that relate to the values that are contained in the php variable. So they cannot be clicked. It would also like to change the colour of the cell that the check box is contained in. It is important that the checkboxes or at least the table that contain the checkboxes remain, as it represents the layout of a theatre. Cheers for your help Good evening all, I have a bit of an issue with checkboxes - basically I need to allow only 1 selection and then have a comments box show when a checkbox is checked. I've gotten the comments box to show when the checkbox is checked but I can't seem to workout how to allow only one. I'd really like the user to be able to change their mind and make a different selection but only have 1 be selected at a time (sort of like radio buttons work). I know it would be much easier and probably better to use radio buttons but that isn't an option with this. (The actual HTML is produced using a style sheet in an application that I am interfacing with so all I can do is use the checkbox.) Here is the code I am using to show or hide the comments box. Code:
function HideComments()
{
var a1 = document.getElementById("crmForm_answer1").checked;
var a8 = document.getElementById("crmForm_answer8").checked;
var a2 = document.getElementById("crmForm_answer2").checked;
var a3 = document.getElementById("crmForm_answer3").checked;
var a4 = document.getElementById("crmForm_answer4").checked;
var a5 = document.getElementById("crmForm_answer5").checked;
var a6 = document.getElementById("crmForm_answer6").checked;
var a7 = document.getElementById("crmForm_answer7").checked;
var a9 = document.getElementById("crmForm_answer9").checked;
var a10 = document.getElementById("crmForm_answer10").checked;
if(a1==true)
{
document.getElementById("crmForm_answer1_value").parentNode.parentNode.style.display = 'block';
}
else
document.getElementById("crmForm_answer1_value").parentNode.parentNode.style.display = 'none';
if(a8==true)
{
document.getElementById("crmForm_answer8_value").parentNode.parentNode.style.display = 'block';
}
else
document.getElementById("crmForm_answer8_value").parentNode.parentNode.style.display = 'none';
if(a2==true)
{
document.getElementById("crmForm_answer2_value").parentNode.parentNode.style.display = 'block';
}
else
document.getElementById("crmForm_answer2_value").parentNode.parentNode.style.display = 'none';
if(a3==true)
{
document.getElementById("crmForm_answer3_value").parentNode.parentNode.style.display = 'block';
}
else
document.getElementById("crmForm_answer3_value").parentNode.parentNode.style.display = 'none';
if(a4==true)
{
document.getElementById("crmForm_answer4_value").parentNode.parentNode.style.display = 'block';
}
else
document.getElementById("crmForm_answer4_value").parentNode.parentNode.style.display = 'none';
if(a5==true)
{
document.getElementById("crmForm_answer5_value").parentNode.parentNode.style.display = 'block';
}
else
document.getElementById("crmForm_answer5_value").parentNode.parentNode.style.display = 'none';
if(a6==true)
{
document.getElementById("crmForm_answer6_value").parentNode.parentNode.style.display = 'block';
}
else
document.getElementById("crmForm_answer6_value").parentNode.parentNode.style.display = 'none';
if(a7==true)
{
document.getElementById("crmForm_answer7_value").parentNode.parentNode.style.display = 'block';
}
else
document.getElementById("crmForm_answer7_value").parentNode.parentNode.style.display = 'none';
if(a9==true)
{
document.getElementById("crmForm_answer9_value").parentNode.parentNode.style.display = 'block';
}
else
document.getElementById("crmForm_answer9_value").parentNode.parentNode.style.display = 'none';
if(a10==true)
{
document.getElementById("crmForm_answer10_value").parentNode.parentNode.style.display = 'block';
}
else
document.getElementById("crmForm_answer10_value").parentNode.parentNode.style.display = 'none';
}
Thanks in Advance Sam have a simple calculator i made with checkboxes and some Js. the problem is that it does not work in FF. any idea how this can work for IE Safari AND FF Code:
function getPrice(amount, boxName){
total = eval() ;
checked = document.getElementById(boxName).checked
if (checked){
total = parseFloat(form1.Total2.value) + parseFloat(amount);
}else{
total = parseFloat(form1.Total2.value) - parseFloat(amount);
}
total.toFixed(2);
form1.Total2.value = total
document.getElementById("total").innerHTML = "Total $"+total;
}
This script works via "elem.checked" which is great for checkboxes (see http://javascript.internet.com/forms...heckboxes.html), but I need it to work with image buttons instead where there is no "checking" going on. Is this possible? I tried elem.onclick and elem.clicked but neither works. I don't know enough about onclick conditionals. Please help. Code: function UpdateCost() {
var sum = 0;
var gn, elem;
for (i=0; i<4; i++) {
gn = 'game'+i;
elem = document.getElementById(gn);
if (elem.checked == true) { sum += Number(elem.value); }
}
document.getElementById('totalcost').value = sum.toFixed(2);
}
tl;dr: Want to make the above work with <a onclick="UpdateCost()"><img></a>, not <input type="checkbox" onclick="UpdateCost()"> I am trying to get a link that when clicked it will check all the checkboxes in my form. My problem is that my values are stored in an array: <INPUT TYPE=\"checkbox\" name=\"emailArray[]\" value=\"$email\"> print"<br><a href=\"#\" onClick=\"checkAll()\">check all</a><br>"; Here is my javascript function : function checkAll(){ alert('hi'); var df = document.selectEmailForm.elements; for (var i = 0; i < df.length; i++) { if (df[i].name == "emailArray[]" ) { document.selectEmailForm.emailArray[i].checked=true; } } } Any ideas? Any help is greatly appreciated. Thanks for your time! Hello, I have a form generated by mySQL and PHP, and inside the form (named 'UpdateDB') each line has checkboxes, like so: Code: <input type="checkbox" name="checkbox[]" value="96" onclick="highlight(this,'check_96')"> The onclick is to highlight the row, that works fine. However, I wrote a javascript function that toggles the select all the checkboxes or none. This is done by an image: Code: <img src="img/select.png" align="top">
<a href="#" onClick="togBox('updateDB');"><img src="img/all.png" name="listToggle" align="top"></a>
Easy, right? So heres the Javascript function that the above image (the 'none' part) links to: Code: function togBox(form)
{ var myForm = document.forms[form];
document.listToggle.src=='http://gospeltruth.tv/admin/img/all.png' ? toggle = true : toggle = false;
(toggle) ? document.listToggle.src='img/none.png' : document.listToggle.src='img/all.png';
for( var i=0; i < myForm.length; i++ )
{
(toggle) ? myForm.elements[i].checked = 'checked' : myForm.elements[i].checked = '';
}
}
Its a brilliant function if I do say so myself, and this is what I dont get: two days ago, it was working fine, today, its not working at all. The image changes, but IE flags up the 'myForm.length' as an error. How was it working 2 days ago and not today, when I havent touched it? Can anybody advise why its not currently working? Thanks for your help, ~Chud37 irst post here, i'll try to be simple: I need to create a form where participants of a medical convention register to classes, each class lasts 3 hours, so a person who wants to attend to class starting at 10 am cannot register to 11 am, 12pm and 1pm classes, but he can register to 2pm and so on. There are 3 different classes per hour. i thought doing this using javascript, but i'm absolutely lost. Can you please give me a hint on how to do this? Thanks!! this is the part of the form that has the checkboxes. <form method="post" action="process.php"></form> <input type="checkbox" value="101" name="convention1"> 10 am: Cariovascular desease<br> <input type="checkbox" value="102" name="convention2"> 10 am: Changes on toracic surgeon<br> <input type="checkbox" value="103" name="convention3"> 10 am: New drugs on heart<br> <input type="checkbox" value="111" name="convention4"> 11 am: New drugs on heart (II)<br> <input type="checkbox" value="112" name="convention5"> 11 am: Dynamic process on blood pressure<br> <input type="checkbox" value="113" name="convention6"> 11 am: Aortic disease<br> <input type="checkbox" value="121" name="convention7"> 12 am: Pulmonar Pressure<br> <input type="checkbox" value="122" name="convention8"> 12 am: Open table<br> <input type="checkbox" value="131" name="convention9"> 1 pm: Neurological aspects on heart rate<br> <input type="checkbox" value="132" name="convention10"> 1 pm: Cardiovascular disease (II)<br> <input type="checkbox" value="133" name="convention11"> 1 pm: Mioresponse on heart failure<br> <input type="checkbox" value="141" name="convention12"> 2 pm<br> <input type="checkbox" value="142" name="convention13"> 2 pm<br> <input type="checkbox" value="143" name="convention14"> 2 pm<br> <input type="checkbox" value="151" name="convention15"> 3 pm<br> <input type="checkbox" value="152" name="convention16"> 3 pm<br> <input type="checkbox" value="153" name="convention17"> 3 pm<br> <input type="submit"></input> </form> Hello, today I am trying to allow a user to easily uncheck/check all checkboxes in a form by checking or unchecking a checkbox. The checkboxes would be in a form like so: Code: <form action="" method="post"> <input type="checkbox" name="checked[]" value="1"> <input type="checkbox" name="checked[]" value="2"> <input type="checkbox" name="checked[]" value="3"> <input type="checkbox" name="checked[]" value="4"> </form> I use an event handler to call a function: Code: <input type="checkbox" name="checkall" onchange="checkall('checked[]', this.checked)">
And here is the function: Code: function checkall(box_name, current_state) {
all = document.getElementsByName(box_name);
action = (current_state == "checked") ? "false" : "true";
for (i = 0; i < all.length; i++) {
all[i].checked=action;
}
}
The event handler should pass the name of the checkboxes and whether the "check all" checkbox is currently checked or not to the checkall() function. Nothing happens when I check/uncheck the "check all" function. Help? Hi Guys, I'm currently working on a page working with separate categories and a whole lotta check boxes. My objective is to have one checkbox deselect the other checkboxes in its category without interfering with the rest. How would I go about doing this assuming the id tag is already in use and differs per tag? I was thinking about cycling through all checkbox tags and sorting them out via class but I'm looking for something possibly more efficient. Hi, I have a few checkboxes in a form. Some of them work independently, but some make the others go on and off. Specifically the lower ones are controlling the upper ones. Can anyone explain why please? Code: <td> <input type="checkbox" name="weddingitem1" value="Toppers" id="Toppers"/><label for="Toppers" >Toppers<br /> <input type="checkbox" name="weddingitem2" value="Champers" id="Champers"/><label for="Champers" >Champers<br /> </td> Hello. How can you modify this code so that if you click a checkbox that is ALREADY CHECKED, it will remain checked? By the way, I have searched the web on how to do this and the general consensus seems to be "use radio buttons instead", but I would not like to use radio buttons. I would like to use checkboxes, I think they look better for what I am trying to do. Thanks for any help Code: <input type="checkbox" id="ckbox1" onclick="if(this.checked){ document.myform.ckbox1.checked=true; document.myform.ckbox2.checked=false; document.myform.ckbox3.checked=false;}" checked="checked" />Best Match
<input type="checkbox" id="ckbox2" onclick="if(this.checked){ document.myform.ckbox1.checked=false; document.myform.ckbox2.checked=true; document.myform.ckbox3.checked=false;}" />All Words
<input type="checkbox" id="ckbox3" onclick="if(this.checked){ document.myform.ckbox1.checked=false; document.myform.ckbox2.checked=false; document.myform.ckbox3.checked=true;}" />Exact Phrase
from a browser address bar command? say if a page has hundreds of checkboxes, and I needed to check them all, but only 2-3 should be left out, how do i input a browser command line, to check it all, so i will manually uncheck the 2 or 3 thats not needed?
