Get values of all textboxes with same name attributes in jquery - javascript

I need to get values of all textboxes with same name attributes using jquery.
<input type="text" id="text1" name="text[]">
<input type="text" id="text2" name="text[]">
<input type="text" id="text3" name="text[]">
How can I get all values of textbox text[] and compare it using jquery.
I tried using
var values = $("input[name='text[]']")
.map(function(){return $(this).val();}).get();
but am no successful.

You can use map method and store the values into an array.
$(function(){
var values = $('input[name="text[]"]').map(function(){
return this.value
}).get()
})

This one should work :
$('input[name="text[]"]');
You can loop on it to get all values.
$('input[name="text[]"]').each(function() {
alert($(this).val());
});

Let's split the requirement into smaller problems.
First you want to select all those inputs.
var $inputs = $("input[name='text[]']")
It returns a jQuery object, containing all the input named text[].
You also might not need to use square brackets into the name.
var inputs = $inputs.get();
Extract the matching elements into a plain Array, so that we can now access Array's prototype methods, such as Array.prototype.map.
var values = inputs.map(function takeValue(input) {
return input.value;
});

Use a selector like this:
$('input[type="text"][name="text[]"')

var textboxcount = document.getElementsByName("text").length;
var textvalue="";
for (var i = 0; i < textboxcount ; i++) {
textvalue= textvalue + document.getElementsByName("text").item(i).value;
}
alert(textvalue);

Getting value of multiple text inputs by class name and only returning value from the one that has value

I have multiple text inputs that all share the same class name.
Assuming the code has been written so that only one of those text inputs can have value at any one time, is it possible to search for the value of those text inputs by class name and only return the value of the one that has data written in it by the user?
For the purpose of this question, how would I get that value to be returned in the alert box in the code below?
var input = document.getElementsByClassName("input").value;
alert("input");
If it isn't possible using class names, is there an alternative solution that would achieve the same effect?
I would rather avoid having to give each text input an id and write code for each one, hence wanting to use class names.
//find all the elements, filter out the ones without a value, get the value
$('.theClass').filter(function(){ return this.value.trim(); }).val()
var $inputs = $('.aClass');
$inputs.on('input', function(){
$inputs.not(this).prop('disabled', this.value.trim());
});
$('button').on('click', function(){
console.log(
$inputs.filter(function(){ return this.value.trim(); }).val()
);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div><input type="text" class="aClass"></div>
<div><input type="text" class="aClass"></div>
<div><input type="text" class="aClass"></div>
<div><input type="text" class="aClass"></div>
<div><button>Get Value</button></div>
Please try this below code,
var matches = document.getElementsByClassName('input');
for (var i=0; i<matches.length; i++) {
//do action
console.log(matches[i].value)
}

Putting element names in a list "[]" with Javascript

I want to put all input element names of a specific parent to a list with Jquery.
<form id="got">
<input name="jon">
<input name="oberyn">
<input name="tyrion">
</form>
var inputs = ["jon", "oberyn", "tyrion"];
So i can manipulate them with forEach.
How can i do that?
You could use .map method.
var inputs = $('#got').find('input').map(function() {
return $(this).attr('name');
}).get();
Try using arrays - jQuery .each().
Demo Fiddle
var arr = [];
$('#got input').each(function(){
arr.push($(this).prop('name')); //a simple way : arr.push(this.name);
console.log(arr);
});

How to get values of each input field using jquery having same name?

I am trying to get the values of each of the input field that are under same set. Below is my code:
Input field 1:
<input type="text" maxlength="255" name="amount[]" >
Input field 2:
<input type="text" maxlength="255" name="amount[]" >
and so on....the number of fields are variable.
Now I want to get the values the user typed in each of the field that is named . How to do that in jquery?
I have tried following code but it returns nothing:
$("input[name=amount[]]").val();
you can get all values in an array
var values = $('input[name="amount[]"]').map(function(){
return this.value;
}).get();
console.log(values);
Demo ---> http://jsfiddle.net/BFjp5/
Since there are multiple element with same name you need indexing:
$("input[name='amount[]']")[0].value;
Here is demo
and for getting all elements values:
$("input[name='amount[]']").each(function (i,v) {
alert(this.value);
});
Here is demo
by javascript
function getValues(){
var ids=document.getElementsByName('amount[]');
var ary=new Array();
for(var i=0;i<ids.length;i++){
ary[i]=ids[i].value;
}
return ary;
}
$("input[name='amount[]']")
This will get you a set of elements. You can get value of each of those elements by iterating over them.
$("input[name='amount[]']").each(function(){
$(this).val();
});
Try to pass the attribute value as a string since [ and ] are meta-characters,
var values = $("input[name='amount[]']")
.map(function(){ return $(this).val() })
.get().join('');
DEMO
You don't!
The whole point of ID's in the DOM is that they are unique.

put form elements all form elements into specific object array

UPDATED
How would I get all form elements from a form and format them in an object to match the output of the following object(using only javascript)?
var feature = dojo.byId('searchString').value;
var OBJECTID= dojo.byId('OBJECTID').value;
This is the format I need:
var updates = {attributes:{
OBJECTID:OBJECTID,
SubWS:feature
}};
form elements:
<input type="text" id="OBJECTID" value="" />
<input type="text" id="searchString" value="" />
output:
This is my working script, but the output does not match the above "updates". The final version will loop through many more form fields that will sometimes be updated, so i don't want to hardcode the attributes.
var inputs = document.getElementsByTagName("input");
console.log("inputs array", inputs);
var params = {attributes:{}};
for(var i=0; i < inputs.length; i++){
var curr = inputs[i];
if(curr.getAttribute('type')==='text'){
params[curr.getAttribute('name')] = curr.value;
}
}
this is what it looks like on my actual form. As you can see the object is slightly different.
If i've understood you correctly then you need to change the follow line
params.attributes[curr.getAttribute('name')] = curr.value;
By adding .attributes you should match the structure you are after.

How to parse a variable in Javascript

I'm trying to use this code:
var field="myField";
vals[x]=document.myForm.field.value;
In the html code I have
<form name="myForm">
<input type='radio' name='myField' value='123' /> 123
<input type='radio' name='myField' value='xyz' /> xyz
</form>
But this gives me the error:
document.myForm.field is undefined
How can I get field to be treated as a variable rather than a field?
Assuming that your other syntax is correct (I havne't checked), this will do what you want:
var field="myField";
vals[x]=document.myForm[field].value;
In JS, the bracket operator is a get-property-by-name accessor. You can read more about it here.
Use the elements[] collection
document.forms['myForm'].elements[field]
elements collection in DOM spec
BTW. If you have two fields with the same name, to get the value of any field, you have to read from:
var value = document.forms['myForm'].elements[field][index_of_field].value
eg.
var value = document.forms['myForm'].elements[field][0].value
and, if you want to get value of selected radio-button you have to check which one is selected
var e = document.forms['myForm'].elements[field];
var val = e[0].checked ? e[0].value : e[1].checked ? e[1].value : null;
You have to do it like this:
var field = "myField";
vals[x] = document.myForm[field].value;
or even
vals[x] = document.forms.myForm.elements[field].value;
Based on your tags, it seems that you are using jQuery. If so, you can just do this and it will make your life much easier:
var vals = new Array();
$("form[name='myForm'] :radio").each(function() {
vals.push($(this).val());
});
:-D
