JavaScript - Checkbox Error
Firebug returns an error saying msg.elements is undefined. I'm trying to make a function that will enabled a delete button if any of the check boxes in a list are checked.
Code: function selectone () {
var msg = document.getElementsByName('pm');
var i = 0;
for(i; i < msg.elements.length; i++)
{
if(msg.elements[i].checked == true)
{
document.getElementById('multiple_action').disabled = false;
document.getElementById('drop_button').setAttribute("class", "drop_button");
}
else
{
document.getElementById('multiple_action').disabled = true;
document.getElementById('drop_button').setAttribute("class", "drop_button disabled");
}
}
}

I would really appricate if someone could solve this for me. Regards I am using a checkbox to turn on and off some labels on a line on a google map, which is working fine if the line is already drawn, using this function: Code: function distboxclick(labelsbox) {
if (labelsbox.checked) {
for (var i=0; i<distmarkers.length; i++) {
if (distmarkers[i].mLabel != null) distmarkers[i].mLabel.show();
}
} else {
for (var i=0; i<distmarkers.length; i++) {
if (distmarkers[i].mLabel != null) distmarkers[i].mLabel.hide();
}
}
}
but the thing is that I want the labels to be turned off to begin with and switched on if the box is checked. Which is also fine, using this snippet: Code: if (prevMarker){
var dist = getSegmentDistance(prevMarker.mMarker, distmarker);
var label = new ELabel(point, dist, "labelstyle", new GSize(10,-15));
distmarkers[numMarkers-1].mLabel = label;
distlabels.push(label);
map.addOverlay(label);
label.hide();
drawOverlay();
}
but what I am trying to do now is make sure that if the box is checked before the line starts to be drawn then the labels will come up straight away. So I figured all I had to do was add in the following to the above: Code: if (labelsbox.checked){
label.show(); }
else {
label.hide(); }
and pass the labelsbox variable to the function where that is all happening. But instead I get a "labelsbox is undefined" error... If I take that if statement out I see that labelsbox is defined, but that doesn't really help. I guess I'm putting things in the wrong order or something, but I'm kind of baffled. You can see my test page here. Thanks in advance for any suggestions. I am trying to make a checkbox on the screen so that when I check or uncheck it a word will print on the screen. Unfortunately it is not working. The checkbox shows up but nothing happens when I check/uncheck it. Also, even though that part of the code isn't working everything that comes after it that is suppose to print onto the screen is also not printing. I am assuming it is because there is an error and cannot reach that part of the code. I am used to programming in Java and using eclipse which has a debugger in it and was wondering if there is a nice editor/debugger like eclipse I can use for JavaScript. Thanks. Code: <html>

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. Sorted. Close thread please.

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. Hi all, Can anyone point me in the right direction for some sample code that when the selection on a checkbox changes, either writes or removes some content? In this instance, when the checkbox is unchecked, I want more table rows and columns written with the relevant data within them. Then when checked, I want this data removed. Many thanks 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);

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, i have the next code: PHP Code: Code: <span id="review-buttons-container" class="a-center">
<input type="image" src="<?php echo $this->getSkinUrl('images/btn_place_order.gif') ?>" onclick="review.save();" value="<?php echo $this->__('Place Order') ?>" />
</span>
</p>
</div>
<script type="text/javascript">
//<![CDATA[
var review = new Review('<?php echo $this->getUrl('checkout/onepage/saveOrder') ?>', '<?php echo $this->getUrl('checkout/onepage/success') ?>', $('checkout-agreements'));
//]]>
</script>
and i add the follow JavaScript code to create checkbox (the idea is that only when you with the checkbox checked, the button work) i try: PHP Code: Code: <span id="review-buttons-container" class="a-center">
<form action="" onSubmit="return check(this);">
<input name="chkbox" value="please make sure i'm checked" type="checkbox" />
<input type="image" src="<?php echo $this->getSkinUrl('images/btn_place_order.gif') ?>" onclick="review.save();" value="<?php echo $this->__('Place Order') ?>" />
</form>
</span>
</p>
</div>
<script type="text/javascript">
//<![CDATA[
function check(form){
if( form.chkbox.checked )
return true;
else{
alert("please check the checkbox");
return false;
}
}
var review = new Review('<?php echo $this->getUrl('checkout/onepage/saveOrder') ?>', '<?php echo $this->getUrl('checkout/onepage/success') ?>', $('checkout-agreements'));
//]]>
</script>
but its not work for me my javascript knowledge is not so good, please help me to create this checkbox) Thanks. All, I have the following checkbox code: PHP Code: echo "<input name=\"picbigid[]\" type=\"checkbox\" value=\"$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! |
