I want to add a default value to an input field on an existing form when the page is loaded. All of the inputs on the field have the same name and ID on this form.
<table>
<tr><td>Name:</td><td><input id="MultiLookupPicker" name="MultiLookupPicker"/></td></tr>
<tr><td>Company:</td><td><input id="MultiLookupPicker" name="MultiLookupPicker"/></td></tr>
<tr><td>Department: </td><td><input id="MultiLookupPicker" name="MultiLookupPicker"/></td></tr>
</table>
Here's the example http://jsfiddle.net/ljd144/6ocsLk6k/
How would I add a default value to the input immediately following the text "Company"? Thanks!
The input is not in your td so the find method won't work. You need to select the next td first.
$( "td:contains('Company')").next("td").find("input").val("test");
I updated your fiddle with the right selector
JSFiddle updated
You can't use the same id on multiple element, it's very very bad and will lead to unexpected result.
to add a default value, you can do it in html :
<tr><td>Name:</td><td><input id="MultiLookupPicker" value="yourvalue" name="MultiLookupPicker"/></td></tr>
or in jquery :
$("$MultiLookupPicker").val("yourvalue");
Try it ..but id must be unique
$( "td:contains('Company')").next().find("input").val("test");
NOTE: In your fiddle $( "td:contains('Company')").find("input") it always return empty array bcoz there is no input element that td , so use next() and find the input

I want to get the value of an input. In my application, I want to update an entry in my database for each row. So, when I click on the button, I want the values of the corresponding row.
$('.ajouter_un_sol').click(function(){
var id_sol = $(this).find('.nom_sol').value;
alert(id_sol);
});
I made a jsfiddle for you to see what I'm trying to do. I'm trying to get the value of a row.
Can someone tell me how I should do please ?
use this
$('.button').click(function(){
var age = $(this).parent().parent().children('td').find('.age').val();
alert(age);
})
use .val() in jquery.
The .val() method is primarily used to get the values of form elements
such as input, select and textarea.
var id_sol = $(this).find('.nom_sol').val();
for your scenario use
$(this).parents('tr').find('td .age').val();
Fiddle
Try
var id_sol = $(this).closest("tr").find('.nom_sol').val()
.value is a javscript property so you need to use .val().
You are trying to find the input inside button but actually it is within td so you need to find it in td within the parent tr
In your fiddle, instead of
var age = $(this).find('.age').value;
try
var age = $(this).closest('tr').find('.age').val();
closest('tr') finds the nearest ancestor of type 'tr', and then you search down for the age field from there.
I have a checkbox in a column of an html table. When I check or uncheck it I want some text to be displayed/removed from a text area in the next column of the same row.
I did the following:
$(this).parent().parent().find('textarea').text = 'some text'
and also
$(this).parent().parent().find('textarea').val = 'some text'
but it does not work.
The html is like:
<tr>
<td>
<input type="checkbox" />
</td>
<td>
<textarea>
</td>
</tr>
I want to get the textarea of the same tr of the checkbox I check
UPDATE
I found that I should use .val("some text") but now the function is called only if I click the checkbox in the first row. Not for the rest
The issue is with how you are trying to set the value not how you are finding the element
try this
$(this).closest('tr').find('textarea').val("some text");
See here for more info .val()
UPDATE
an element ID has to be unique so you can't reuse the same one. Give all your checkboxes unique id's i.e "chkOne", "chkTwo" etc. Then use a class on all the checkboxes you wish to run this functionality from. i.e class="chkSelection". Then change your jQuery to look like this
$('.chkSelection').change(function() {
if($(this).is(':checked')){
$(this).closest('tr').find('textarea:first').text('Some text here');
}
});
This way all your checkboxes with a class of "chkSelection" when changed will run the functionality to find the next textarea and set the text.
Just give them identifiers, as surely you'll need to reference them somehow elsewhere (and if your structure changes it won't break as a side-effect) - note the use of val(), too:
<tr>
<td><input id="someName" type="checkbox"/></td>
<td><textarea id="someOther"></textarea></td>
</tr>
Then you can reference them explicitly:
$("#someName").change(function(e) {
$("#someOther").val("some value");
});
Keep it simple.
try this code
$("table input[type=checkbox]").change(function(){
// Your code.
});
Give generic classes to all the checkboxes and textareas... In the .change() function of the checkbox try using this: (Considering the class of the textarea is textarea)
$(this).parent().find('.textarea').html("Your text here");
To check if the checkbox is checked/unchecked, try attr('checked').. Also to get the values of all checked checkboxes, try 'input[type="checkbox"]:checked').val()
my solution
$('table input:checkbox').change(function(){
$(this).parent().next().find('textarea').val("some text");
});
If you want to be able to toggle the text on and off by checking/unchecking the box, something like this would work:
$("input[type=checkbox]").change(function() {
$(this).filter(":checked").parent().next().text('Text!");
$(this).not(":checked").parent().next().text('');
})
This would listen for any change to any checkbox on your page. When a checkbox changes, it will select the checkbox's parent's sibling (the next <td> element after the one surrounding the checkbox) and set its text to 'Text!' if the box is checked, or an empty string if the box is unchecked.
The benefit to using this method, aside from the text on/off functionality, is that you don't need to assign CSS classes/ids for it to work.
have a brief question regarding innerHTML and input values that have been entered. See the brief example below (using jQuery for convenience):
http://jsfiddle.net/F7urT/2/
jQuery:
jQuery(document).ready(function($) {
$('.send').click(function() {
alert( $('.content').html() );
return false;
});
});
html:
<div class="content">
<input type="text" name="input" value="Old Value" />
<input type="button" class="send" value="Send" />
</div>
If you edit the input value, then click the 'Send' button, the alert shows that the innerHTML gotten contains the input with the "Old Value", rather than the value the user has entered. Why is this? And how can we get the HTML as a string with user entered input values?
The new value is stored as a property not an attribute, the value can be obtained by inputelement.value, modifying the value does not affect the attribute. If you want the html with the new value just set the attribute to the new value.
For check boxes and radio buttons set the checked attribute, set the innerHTML for text areas, for selects set the selected attribute on the option
http://jsfiddle.net/mowglisanu/F7urT/5/
this solution is better. works for more inputs.
$('input[type=text]').attr('value', function (i, val) { return val; });
$('input[type=checkbox],input[type=radio]').attr('checked', function () { return this.checked; });
$('textarea').html(function () { return this.value; });
$('select').find(':selected').attr('selected', 'selected');
You can't get it with .innerHTML (.html()). Writing into an element doesn't modify the html markup, nor will it change the value attribute in actual markup.
You can only access the current content by directly asking the element for its .value - value. Using jQuery, you can do that via .val() too.
$('#input_id').attr('value',$('#input_id').val()); will put the value into the html
DanCZ & Musa solutions works pretty good, but I had trouble with the textarea.
I have to implement this in a Typescript project and the only way I've found to make the textarea show the value is this :
textarea.innerHTML = textarea.value;
Hi I want to insert a cookie value which I am getting by using jQuery.
I want to grab the value of the cookie and insert it into the html value attribute.
<input id="visitorcookie" type="hidden" value="<script>$.cookie('visitorCookie');</script>" name="com.silverpop.iMAWebCookie">
Is this correct how I am doing it?
Not at all actually. The value attitribute won't execute any code, it just can store a value.
Do this: when the DOM is ready, select the hidden field by ID with $('#visitorcookie') and set it's value with .val():
$(document).ready(function() {
$('#visitorcookie').val($.cookie('visitorCookie'));
});
More about:
jquery selectors
.val() method
$("#visitorcookie").val($.cookie('visitorCookie'));
$('#visitorcookie').val($.cookie('visitorCookie'));
I am trying to set a value to a hidden form element by selecting their Id and not their name attribute. The hidden element has id="user_lat and name="user_lat". How can I do that?
I seem to be able to select by name:
$("input[name='user_lat']").val(results[0].geometry.location.lat());
MY attempt at selecting by id below does not work:
$("input #user_lat").val(results[0].geometry.location.lat());
If the id is to be applied to the input, the selector can have no spaces:
$("input#user_lat").doSomething();
If you place a space between input and #user_lat, the selector attempts to match a child of the input, which doesn't make much sense. It would be like having the following markup:
<input><el id="user_lat" /></input>
Removing the space matches any input that contains the ID:
<input id="user_lat" />
You must stick them together "input#user_lat"
input #user_lat means:Look for an input and then find inside the element with id user_lat
You are close, take out "input" from the second statement and you should be good.
$("#user_lat").val(results[0].geometry.location.lat());
When you are usign the selector "input #user_lat" your saying the element "user_lat" inside an input. So what you need to do is just delete the space between them, something like this:
$("input#user_lat") ...
