JQuery :: Check A Checkbox When Textarea Is Typed In?
Mar 4, 2011
I think I have what is a simple question: I would like a checkbox to be checked if it is not already when a user types in the text area beside it. Form layout is demo'd below.
<table>
<tr>
<td><input type="checkbox" name="box[1]" value = "x"></td>
<td><textarea name="area[1]">
I am writing an HTML builder. On thing that I think would be helpful is if the user types in
="
A javascript adds another " for the user, but puts the cursor inbetween the two "'s. In other words, the javascript should assist users in writing HTML/Javascript codes. This may also be applied to < & >.
I have found this script that can get your position in a textarea. I also thought this might be of help:
Code: var textarea = document.getElementById('code'); var tmp = textarea.value; textarea.value = textarea.value.substring(0, textarea.selectionStart) + '"' + tmp + textarea.value.substring(textarea.selectionEnd);
Although I have tried, I have not been able to piece the scripts together.
I am at a stand still with trying to figure this out. I have a textarea, i would like to check for links entered by users and replace/remove the anchor attribute from the string. ie. change [URL] to website its more so to validate ( i have a php side working to validate for links but am trying to get jquery to just remove it and maybe say a warning.
I want when checkbox is checked, the span will have 500 USD. When checkbox is unchecked the span will return 0.This is what I've got, have no idea why not work.
Code JavaScript: if ($('#priority').is(':checked')) { $('.presult').text('500 USD');
I'm trying to recreate a behaviour which enables a disabled checkbox after the user has completely scrolled down to the bottom of a textarea ("agree to license terms"). My current state can be found at http:[url]....The checkbox is not being enabled with my approach. I can enable the checkbox if I explicitly set scrollTop to a value, but then I'm not able to scroll anymore at all. So I am guessing it probably has to do with the scroll check not working properly.
How can i check that the value of my checked radiobutton / checkbox (between two or more) is exactly the one i want? at the moment if i check a radiogroup the validation returns always the value of the first radiobutton / checkbox.[code]..
I have a checkbox and when the it's checked I want to increase the row of the textarea
for(i=0; i < chkBoxes.length; i++) { chkBoxes[i].onclick=function() { document.getElementById('addnote').rows =4; // this only increase the textarea of the first row. If I have more than row , it won't work }
I am setting up a form which will ask the user for several questions after which they will then be saved to a database. It all works well with exception of one thing. I am trying the following and can't get it to work.
What I want to do is to to have multiple checkboxes, each of them activating the same textarea and then add information to the textarea. For activating the textarea I am using the following code:
This works, however, how do I add information to the textarea when each of the checkboxes is checked? I tried obj_textarea.value='VALUE' but this will only allow one checkbox to display its value into the textarea. Code:
(1) A <div> tag which contains an individual checkbox labeled as Select All.
(2) A <div> containing a reference to a bunch of check boxes (containing e-mail addresses).
JavaScript code:
How to remove any possible check boxes that are checked and remove them from text field
What happens is that when I click on the Select All check box, it populates my To: text field with all the e-mail addresses.
However, the checkboxes belonging inside emailCheckListId_ul are checked.
How can I set it up so that if I click on Select All, all the checkboxes are populated and when I uncheck on Select All, all the checks are removed from the check boxes and the e-mail addresses are removed from the To: text field?
is there any way to check if any textarea or textfield exists in current document fg function checkifexist(){ if any textarea or textfield exist return true else return false }
I just don't get why it's not working. I must be missing something, but I have no idea what. The FORM tag's NAME and ID elements are "inhouse-f2". What else could it be?
I'm using the following code for a checkbox that when clicked, either checks or unchecks a group of checkboxes on a form. The code works fine, except when there is only one checkbox in the group in which case the check all checkbox doesn't work at all.
The code working with three checkboxes in a group is as follows, but remove two of the three and you will see the code stops working:
<script language="javascript" type="text/javascript"> function checkAll( control, cbGroupName ) { var cbGroup = control.form.elements[cbGroupName], i = 0, cb; while( cb = cbGroup[i++] ) { cb.checked = control.checked; }} </script>
I'm pulling some records out of a database and placing a check box next to each record that the user can check and use the delete button to delete the record.
I'm looking for some help to create a javascript function that I can fire off when the user clicks on delete to check if a any records are checked before submiting the deletion. if no check boxes are checked, I want to alertthe user to make a selection.
I'm thinking about having a loop in this function to loop through the checkboxes and figuer out if at least 1 box is checked. Code:
I have a page that displays records returned from a database and places a check box next to each record that the end user can check if they want to delete a record. The function below checks to make sure that at least 1 checkbox was checked before allowing the delete to be processed.
this function works just fine when I have more than 1 recored returned, but if I only have 1 record displayed on the page and check it and hit the delete button, I get this error
"Checked" is null or not an object
is there a way to modify the function to fix this problem.
function isCheckBoxChecked(boxgrp) // This function is used to check if any check boxes // are checked before processing { var i = boxgrp.length; do if (boxgrp[--i].checked) return true while (i); alert('Select an Item to Delete'); return false }
When a checkbox is checked, I would like a group of checkboxes on a page to be automatically checked.
I was thinking of going about it like this:
- value of top checkbox = check1 - values of all checkboxes that should be automatically checked (when top checkbox is checked)= check1_1, check1_2, check1_3 etc
- on the onclick event of the top checkbox, a piece of javascript would be executed that would iterate through all the checkboxes.
x = 1; while (x < 10) { check1_(value of x).checked = true; x++; }
How could i go about doing the above in javascript?
If you've used the Google Gmail spell checker you know that it 'changes' the text area to another type of control that lets them show hyperlinks for the incorrect words. How does Google change the textarea? And what do they change it to? I know it should be pretty simple, I just have no clue because I'm fairly new to DHTML. Any examples would be greatly appreciated.
I would like to get the id of a html check box when the client clicks it. I want to do this on the client side so i need to use java script. I want to be able to do this in both fire fox and ie window.event.srcElement works great for ie but not for firefox do not tell me to use Event.target for firefox because that does not work. At least it is not working for me anyway.
trying to build two different functions:#1: Where cDay would be Mo and loops through 24 times:ie: document.delTime."cDay"1.checked = true;button would be <input type="button" name="Mo" value="Check All Mo" onclick="checkAll(Mo)">I have this but cant work out how to parse cDay into the function correctly:
function checkAll(cDay) { document.delTime.Mo1.checked = true; document.delTime.Mo2.checked = true;
I would like to disable a feature on my site if someone is in a textarea or input text field. Yet I can't seem to figure out how to check for this... Could someone give me an example of how I can determine if a user does not have a text input or textarea selected? Can't seem to get anything I found via google working.
I wrote an application that generates HTML based on some database record set. One of the HTML generated is a checkbox with NAME=StudentID. This is to facilitate user to select this user for further processing. This also means that ALL student have a checkbox named StudentID. I do I ensure that only one checkbox is selected at any time before the user proceed with the processing of the selected student.
