JavaScript - Identifying Checkbox Ids
Hi.
I have a list of checkboxes with Ids that go something like; chk_AGE=16 chk_AGE=17 chk_AGE=18 chk_GENDER=MALE chk_GENDER=FEMALE chk_RANK=OFFICER chk_RANKE=OTHER When a user checks/unchecks '16' (for example), I want javascript to look up how many checkboxes in my form have an Id that begins with "chk_AGE" and return the number in an alert box ("3" in this case). If my user had checked/unchecked "Officer" an alert box would return "2" as there are 2 checkboxes that begin "chk_RANK". Can someone please help with this? I am a complete javascript beginner. Similar TutorialsI have a simple form with an options drop down box: Code: <form method="POST" name="form"> <select autocomplete="off" id="input" name="input" onchange="this.form.submit();goHere();"> <option>Choose...</option> <option>Question1</option> <option>Question2</option> <option>Question3</option> </select> I wish to identify the option chosen in the function but not by its value, by its position: Code: <script>
function goHere(){
var s = document.getElementById("input");
if (s.selectedIndex == -1) return;
var u = s.form.elements[i];
alert(u);
</script>
I was hoping that variable "u" would be either 0, 1, 2, or 3. How can I get a variable to alert me the position of the selected option in the form? I think it is elements[i]. So here's what i want to do: i have 2 checkboxes, when Checkbox A is checked, i want to automatically check the checkbox B. When A is unchecked, then uncheck B how can i do that? thanks a lot ! Hi, If I have two check-boxes and one is already checked and then the is checked, how would I get it to uncheck the first one using JavaScript. Thanks, Cs1h Looking for a simple method to Toggle textbox yes/no using CheckBox This example does not work! But I hope this will help explain what I am trying to do Code: <SCRIPT LANGUAGE="JavaScript">
function YesOrNo() {
if(document.formname.checkboxname.checked)
{
document.formname.textname.disabled='Yes';
}
else
{
document.formname.textname.disabled='No';
}}
</SCRIPT>
<form name="formname">
<input type="text" size="10" name="textname">
<input type="checkbox" onclick="YesOrNo()" name="checkboxname" value="Yes">
</form>
I was trying to get total amount from these all checkbox, when I submit, but I don't know somewhere wrong. Please help me out. Here is my code: <html xmlns = "http://www.w3.org/1999/xhtml"> <head> <title> Form </title> <script language = "JavaScript"> // The event handler functions for the check boxes function appleHandler() { var number = document.orderForm.apples.value; total = total + number * 0.59; } function orangeHandler() { var number = document.orderForm.oranges.value; total = total + number * 0.49; } function bananaHandler() { var number = document.orderForm.bananas.value; total = total + number * 0.39; } // The event handler function to produce the total cost message // when "submit" is clicked function finish() { total = total * 1.05; alert("Thank you for your order \n" + "Your total cost is: $" + total + "\n"); } </script> </head> <body> <h3> Order Form </h3> <form name = "orderForm" onSubmit = "finish()"> <p> <input type = "checkbox" name = "apples" size = "3" onClick = "appleHandler()" /> Apples </p><p> <input type = "checkbox" name = "oranges" size = "3" onClick = "orangeHandler()" /> Oranges </p><p> <input type = "checkbox" name = "bananas" size = "3" onClick = "bananaHandler()" /> Bananas </p><p> <input type = "reset" name = "reset" /> <input type = "submit" name = "submit" /> </p> </form> </body> </html> I am making a google CSE for a client site and I need to concatenate checkbox values together on the end of another form value. So I have a text box and the checkboxes: Code: <input name="q" cid="q" size="25" maxlength="50" value"off road tires"> <input type="checkbox" name="q" id="q" value="cooper|hankook" /> <input type="checkbox" name="q" id="q" value="Mickey Thompson|Bfgoodrich|GBC" /> <input type="checkbox" name="q" id="q" value="Hoosier|Nitto" /> For Google the URL string needs to be like this: Code: results.html?q=off road tires AND inurl:cooper|hankook|Mickey Thompson|Bfgoodrich|GBC this string says the person did not check the last box. I am having a hard time trying to do this. If you guys know a better way to accomplish the same thing I am all ears but I thought I would bring it to the experts and see what they had to say. Thanks for the help! Hi, I have a checkbox and when I "check" I want to add a <p> inside of an <div> and when I "uncheck" I want to remove the <p> from <div>. I've tried this but it's not working Code: $('#checkbox').change(function(){
$('div').html('<p>Some Text</p>');
}, function() {
$('div').remove('<p>Some Text</p>');
});
I hope you can help.. Regards All, I have the following code: Code: var poststr = "statusupdate=" + encodeURI( document.getElementById("statusupdate").value ) +
"&user_name=" + encodeURI( document.getElementById("user_name").value ) +
"&twitteryes=" + encodeURI ( document.getElementById("twitteryes").checked ) +
"¤tstatus=" + encodeURI( document.getElementById("currentstatus").value );
It seems to be failing on the Code: "&twitteryes=" + encodeURI (document.getElementById("twitteryes").checked )
If I remove the part I just showed it works fine. This is the HTML code: Code: <input type="checkbox" name="twitteryes" value="yesplease" /> Thanks in advance. All, I have the following checkbox code: PHP Code: echo "<input name=\"picbigid[]\" type=\"checkbox\" value=\"$pic[src_big]\">"; I then want to select all the checkboxes so I have this code: [PHP] echo "<input type=\"button\" name=\"CheckAll\" value=\"Check All\" onClick=\"checkAll(document.photos.picbigid)\"> <input type=\"button\" name=\"UnCheckAll\" value=\"Uncheck All\" onClick=\"uncheckAll(document.photos.picbigid)\">"; [PHP] My JS function is: Code: function checkAll(field)
{
for (i = 0; i < field.length; i++)
field[i].checked = true ;
}
function uncheckAll(field)
{
for (i = 0; i < field.length; i++)
field[i].checked = false ;
}
If I do it like this: PHP Code: echo "<input name=\"picbigid\" type=\"checkbox\" value=\"$pic[src_big]\">"; It works but I can't have it like that because the form posts to another PHP page that needs the input name as an array. Any ideas? Thanks! Hello I have a site of classifieds ads.... user is choosing what he want to see/search and then a table is printed on the screen(with all the requested results) My question is... Is there a way to add a "CHECK BOX" to each of the ads and the user is checking what he wants to see later on. after he will have a button "see my checked ads" and a page will open with ONLY the ads that he checked before Any suggestions? Thanks a lot Danny Hi, I have the following codes but my checkbox is not appearing. The values of the checkbox do print out in the alert. Can anyone tell me what is wrong with it? Thank you! Code: var table = document.getElementById('maintable');
var i; // iterator
var item; // pointer to item in received list
for(i = 0;
(item = contacts.ReturnValue.getNext()) != undefined;
++i) {
table.insertRow(i + 1);
var result = "<td>";
if(item.FirstName != undefined) {
result += item.FirstName.Value;
}
result += "</td><td>";
if(item.LastName != undefined) {
result += item.LastName.Value;
}
result += "</td><td>";
if(item.MobilePhoneGen != undefined) {
result += item.MobilePhoneGen.Value;
}
result += "</td><td>";
if(item.EmailGen != undefined) {
result += item.EmailGen.Value;
}
var td1 = document.createElement("td");
var chkbox = document.createElement('input');
chkbox.type='Checkbox';
table.rows[i + 1].innerHTML = result;
chkbox.value=item.MobilePhoneGen.Value;
td1.appendChild(chkbox);
alert(chkbox.value);
}

I would really appricate if someone could solve this for me. Regards Hi thier, I am using PHP to generate a page with a list of checkbox's on it. Then I am using JavaScript to validate that the user has selected at lest 1 of the given box's before I do a post back. But I cannot get my Javascript to see my CheckBox Array. Any help you can offer would be very useful thank you all in advance. Here is my PHP code used to build to Checkbox list. Code: while ($row = mysql_fetch_array($data, MYSQL_ASSOC))
{
if(is_null($row['Team_Number']))
{
$str1 = sprintf('<input type="checkbox" name=\'People\' value="%s">',$row['Member_ID']);
}
else if($row['Team_Number'] == $_REQUEST['T'])
{
str1 = sprintf('<input type="checkbox" name=\'People\' value="%s" checked>',$row['Member_ID']);
}
else
{
$str1 = sprintf('<input type="checkbox" name=\'People\' value="%s">',$row['Member_ID']);
}
$str = sprintf('%s,%s (%s)',$row['First'],$row['Last'],$row['Nick_Name']);
echo('<tr><td width ="10%" align="center">');
echo($str1);
echo('</td><td width="90%" align="Left">');
echo($str);
echo('</td >');
echo('</tr></td>');
}
And here is my Javascript, I've added the whole function incase it's not clear just from a code segment. Code: function TeamSetup()
{
var required = document.form1.BowlersPerTeam.value;
var total = document.form1.People.length;
var Tm = document.form1.TeamName.value;
var cnt = 0;
var peopleIDs = "";
var test = document.getElementsByName('People');
if(isArray(document.form1.People))
{
for(var i=0; i < total; i++)
{
if(document.form1.People[i].checked)
{
if(peopleIDs.length > 0)
{
peopleIDs = peopleIDs +",";
}
peopleIDs = peopleIDs + document.form1.People[i].value.toString();
cnt++;
}
}
}
else
{
if(document.form1.People.checked)
{
cnt=1;
peopleIDs = peopleIDs + document.form1.People.value.toString();
}
}
if(Tm.length > 0)
{
if(cnt == required || cnt > 0)
{
//Hand off to next step for completeing Processing.
var myForm = document.createElement("form");
myForm.action=window.location;
myForm.method="Post";
myForm.appendChild(createformInput("Process","PP"));
myForm.appendChild(createformInput("people",peopleIDs));
myForm.appendChild(createformInput("Team",GetQueryString("T")));
myForm.appendChild(createformInput("League",GetQueryString("L")));
myForm.appendChild(createformInput("TeamName",Tm));
document.body.appendChild(myForm);
myForm.submit();
}
else
{
alert('You need to Select at least 1 player');
}
}
else
{
alert('You need to enter the team name!');
}
}
Hi everyone; I have created a JavaScript function to show either a enabled or a disabled text input field depending on whether a checkbox has been clicked or not. It works great for that purpose. However, when I use it for more than one text input field and I submit the form, it goes back to its disabled form. This is a problem if you by mistake submit the form without filling all the fields. As I said, the submit button makes the form go disabled. Is there a way to either not have the form go disabled after submission or to have a "Oncheck" function so I can use $_SESSION to keep the checked attribute? Thanks in advance for all your help Code: <html>
<head>
<style type="text/css">
#Active {
display:none;
}
</style>
<script type="text/javascript">
function toggle() {
if (document.getElementById) {
if (document.getElementById("checkbox").checked == true) {
document.getElementById("Active").style.display = "block";
document.getElementById("Inactive").style.display = "none";
} else {
document.getElementById("Inactive").style.display = "block";
document.getElementById("Active").style.display = "none";
}
}
}
</script>
</head>
<body>
<?php
echo "Add Field";
echo "<input type=\"checkbox\" name=\"check\" id=\"checkbox\" onClick=\"toggle();\" value=\"v\"/>";
echo "<form method=\"post\">";
echo "<div id=Active>";
if(isset($_SESSION['test']) && $_SESSION['test']!="")
{
echo "<input name=\"test\" value=\"". $_SESSION['test']."\" type=\"text\" />";
}
elseif(isset($_POST['test']) && $_POST['test']!="")
{
echo "<input name=\"test\" value=\"". $_POST['test']."\" type=\"text\"/>";
}
else
{
echo "<input name=\"test\" type=\"text\"/>";
}
echo "<input type=\"text\" name=\"test2\" >";
echo "</div>";
echo "<div id=Inactive>";
echo "<input type=\"text\" disabled>";
echo "<input type=\"text\" disabled>";
echo "</div>";
echo "<input type=\"submit\">";
echo "</form>";
$test = $_POST['test'];
$_SESSION = $_POST['test'];
$test2 = $_POST['test2'];
$_SESSION = $_POST['test2'];
echo $test;
?>
</body>
