:contains only looks at the content of elements. input elements have no content. You have to use .filter() [docs] instead:
$('input[name*="new"]').filter(function() {
return this.value.indexOf('has') > -1;
}).css(...);

I'm trying to rewrite google chrome extensions. I want to get #spam_key s #service_codes value in this HTML response.
I have not used JavaScript.
How can I get HTML element id (spam_key, service_code) and value by JavaScript?
DOM has a document object , you can use it like this to get the HTML element what you want
document.getElementById("id")
Now to get value, just use value property of this element.
document.getElementById("id").value
You want to retrieve the spam_key element and service_code element's values?
var spam_key = document.querySelector('#spam_key');
var service_code = document.querySelector('input[name=service_code]');
console.log(spam_key.value);
console.log(service_code.value);
You can learn more about selection element from javascript at here
You can get value of an HTML input element using:
var spam_key = document.getElementById('spam_key').value;
var service_code = document.getElementById('service_code').value;
Try this, It should give the value of spam_key
document.getElementById('spam_key').value;
If you have jQuery included you can get it by following: $("#spam_key").val()
I have a DOM structure similar to this:
<div id="ans1">
<input id="in1" />
<input id="in2" />
</div>
<div id="ans2">
<input id="in1" />
<input id="in2" />
</div>
How can I select some of the descendants of an ancestor?
Something like:
$("#ans1 #in1, #ans1 #in2")
If you replace your 'id's with classes (since ids should be unique), then,
<div id="ans1">
<input class="in1" />
<input class="in2" />
</div>
<div id="ans2">
<input class="in1" />
<input class="in2" />
</div>
Then, to select all the descendants of id=ans1 having class="in1", you go like,
$('#ans1 .in1')
This will return an array of all the .in1 class elements inside id=ans1 element
You can use the children function
$("#ans1").children("#in1, #in2")
You should use unique ids thought the DOM, use classes to specify elements that are the same in nature.
change your children to have same class of in1
$("#ans1 > .in1")
Will select all direct descendants of ans1 with class of in1.
How to take content from a div class one by one and then load it into array? Then I need to insert these one by one to some other div class.
Basically, I have 2 forms, one of which is dummy and this dummy gets its content from CMS. The dummy form is hidden, while real form is shown, but empty at first.
I need to use jquery to take dummy text from form and insert it to real form.
Something like this:
<form name="real" method="post" action="">
<input type="text" name="first" id="a"/>
<input type="text" name="second" id="b"/>
<input type="text" name="third" id="c"/>
<input type="text" name="fourth" id="d"/>
<input type="submit" value="submit"/>
</form>
<form name="extract" style="display:none;">
<div class="generic">data_1</div>
<div class="generic">data_2</div>
<div class="generic">data_3</div>
<div class="generic">data_4</div>
</form>
must become something like this:
<form name="real" method="post" action="">
data_1 <input type="text" name="first" id="a"/>
data_2 <input type="text" name="second" id="b"/>
data_3 <input type="text" name="third" id="c"/>
data_4 <input type="text" name="fourth" id="d"/>
<input type="submit" value="submit"/>
</form>
Is there a way to do this?
Thanks!
There are many ways to do this. For example:
$('[name=extract] div').each(function(index){
$('[name=real] input:eq('+index+')').before($(this).text());
});

I'll offer this version:
$('.generic').each(
function(i){
$('input:text').eq(i).val($(this).text());
});

I have some form elements in a div on a page:
<div id="box">
<div id="template">
<div>
<label for="username">Username</label>
<input type="text" class="username" name="username[]" value="" / >
<label for="hostname">hostname</label>
<input type="text" name="hostname[]" value="">
</div>
</div>
</div>
using jquery I would like to take a copy of #template, manipulate the values of the inputs and insert it after #template so the result would look something like:
<div id="box">
<div id="template">
<div>
<label for="username">Username</label>
<input type="text" class="username" name="username[]" value="" / >
<label for="hostname">hostname</label>
<input type="text" name="hostname[]" value="">
</div>
</div>
<div>
<label for="username">Username</label>
<input type="text" class="username" name="username[]" value="paul" / >
<label for="hostname">hostname</label>
<input type="text" name="hostname[]" value="paul">
</div>
</div>
I am probably going about this the wrong way but the following test bit of javascript code run in firebug on the page does not seem to change the values of the inputs.
var cp = $('#template').clone();
cp.children().children().each( function(i,d){
if( d.localName == 'INPUT' ){
$(d).val('paul'); //.css('background-color', 'red');
}
});
$("#box").append(cp.html());
although if I uncomment "//.css('background-color', 'red');" the inputs will turn red.
Why not just use a selector for input elements with the clone as root like so:
$( "input", cp ).val("paul");
instead of using the calls to children?
EDIT: It looks like as of jQuery 1.4, when you call clone, it should also copy the data of the elements instead of just the markup. That may solve your problem of having to copy over the values directly. Relevant piece of documentation (emphasis mine):
withDataAndEventsA Boolean indicating whether event handlers should be copied along with the elements. As of jQuery 1.4 element data will be copied as well.
I slightly modified your HTML by assigning a "hostname" class to the hostname input.
Here's the updated HTML:
<div id="box">
<div id="template">
<div>
<label for="username">Username</label>
<input type="text" class="username" name="username[]" value="" / >
<label for="hostname">hostname</label>
<input type="text" class="hostname" name="hostname[]" value="">
</div>
</div>
</div>
And here's a JS:
$(function() {
$('#template div:first').clone().appendTo("#box");
$('#box div:last .username').val("Paul");
$('#box div:last .hostname').val("google");
});

I'm using the jQuery .serialize function and can't get it to serialize the proper form on submit.
my js code:
function getquerystring(form) {
return $("form").serialize();
}
my forms:
<div class="leave_message_box">
<form name="leave_message_form">
<input type="text" name="clock_code" placeholder="Clock Code" />
<input type="text" name="message" placeholder="Message (Blank for none)"/>
<input type="hidden" name="type" value="leave_message" />
<input value="Leave Message" type="button" onclick='JavaScript:xmlhttpPost("clockin.php", "leave_message_form")'></p>
</form>
</div>
<div class="outside_job_box">
<form name="outside_job_form">
<input type="text" name="clock_code" placeholder="Clock Code" />
<input type="text" name="message" placeholder="Message (Blank for none)"/>
<input type="hidden" name="type" value="ouside_job" />
<input value="Outside Job" type="button" onclick='JavaScript:xmlhttpPost("clockin.php", "outside_job_form")'></p>
</form>
</div>
I must be doing something wrong in passing the variable. the full code # pastie. The function I have does work, however, its always the last form that gets submitted.
Using this code:
$("form")
will find all the <form> elements in your document.
Given that form is a string containing the name of the form, what you want instead is this:
$("form[name='" + form + "']")
Looking at your supplied code, I have this suggestion. Instead of passing the form name to your function, why not just pass the form itself?
<button onclick="xmlhttpPost('blah', this.form)">
You also don't need to put javascript: in the onclick, onfocus, onwhatever properties.
I would suggest putting an ID attribute on the form and then using that ID as an explicit selector for jQuery:
<div class="outside_job_box">
<form id="outside_job_form" name="outside_job_form">
<input type="text" name="clock_code" placeholder="Clock Code" />
<input type="text" name="message" placeholder="Message (Blank for none)"/>
<input type="hidden" name="type" value="ouside_job" />
<input value="Outside Job" type="button" onclick='JavaScript:xmlhttpPost("clockin.php", "outside_job_form")'></p>
</form>
</div>
Then you would select and serialize it like this;
var f = $("#outside_job_form").serialize();
Not only making your code more effecient but more readable, in my opinion.
If the sole purpose is to encode simple text into URL format then use encodeURIComponent().
