<input name="hello">value1
<input name="hello">value2
<input name="hello">value3
<input name="hello">value4
var a = getElementsByName('hello')
Now, how do I create an array that contains (value1,value2,value3,value4)?
I thought of using makeArray, but it returns just the objects not the values.
You can iterate over them, or use map.
var items = Array.prototype.map.call(a, function(el){
return el.nextSibling.textContent;
});
demo
var items = [];
for (var i=0; i<a.length; i++) {
items.push(a[i].nextSibling.textContent);
}

First of all your html should look like that:
<input name="hello1" value="value1" type="text" />
<input name="hello2" value="value2" type="text" />
<input name="hello3" value="value3" type="text" />
<input name="hello4" value="value4" type="text" />
I.e. if you are using text boxes your name attribute should be different. Otherwise you can't get the values. And of course the values are actually attributes. Here is a pure javascript code which could do what you want:
var inputs = document.querySelectorAll("input[type='text']");
var result = [];
for(var i=0; field=inputs[i]; i++) {
result.push(field.value);
}
alert(result);
And here is a jsfiddle demonstrating the example http://jsfiddle.net/krasimir/nbmjG/
You should do this like:
HTML:
<input type="text" id="hello1" value="value1">
<input type="text" id="hello2" value="value2">
<input type="text" id="hello3" value="value3">
<input type="text" id="hello4" value="value4">
JS:
alert('ready?');
var n = 4;
var arr = new Array(n);
for(var i = 0; i < n; i++) {
arr[i] = document.getElementById('hello' + (i+1)).value;
}
alert(arr);
DEMO
Your inputs have to be like so: Demo
<input name="hello" value="value1">
<input name="hello" value="value2">
<input name="hello" value="value3">
<input name="hello" value="value4">
Then following will return array of values:
var arr = Array.prototype.map.call(document.getElementsByName('hello'), function(elem){
return elem.value;
});
You need to use []
<input name="hello[]">value1</input>
<input name="hello[]">value2</input>
<input name="hello[]">value3</input>
<input name="hello[]">value4</input>

Normally if I add a new input tag I also have to add in Javascript.
I try to collect all value from input tag,
So how to pass value into an object by loop
use tag input name to be object key name also.
Try to use for count
document.getElementById("form1").elements.length
seem it collected the button tag also, how to void it
<form name="form1">
<input type="text" name="value1">
<input type="text" name="value2">
<input type="text" name="value3">
<input type="text" name="value4">
<input type="button" id="save" onClick="fc1()" value="Save">
</form>
for(i=0;......)
{
obj.value+'i' = document.forms["form1"]["value"+ (i+1)].value;
}
Same result as this.
function fc1(){
this.value1 = document.forms["form1"]["value1"].value;
this.value2 = document.forms["form1"]["value2"].value;
this.value3 = document.forms["form1"]["value3"].value;
this.value4 = document.forms["form1"]["value4"].value;
const obj = {
"value1": this.value1,
"value2": this.value2,
"value3": this.value3,
"value4": this.value4
};
}
I usually grab inputs by their ID or class:
<input type="text" id="value1">
then grab the value:
const value1 = document.getElementById('value1').value
to cut down on code, maybe throw it in an array:
const valueArray = [value1, value2, value3]
then you can do something like this:
const allValues = {}
valueArray.forEach((value, index) => {
allValues[`value${index + 1}`] = value
})
now when you log allValues you should have what you want. Note, I am using some es6.
What about this ?
var obj = {};
var form = document.getElementById("form1");
form.children.forEach(function(elm){
if(elm.type === 'text'){
obj[elm.name] = elm.value;
}
});
console.log(obj);
try giving same 'class' or 'name' attribute to the text fields.
try var x = document.getElementsByClassName("example");
which gives you the list of all elements with the class name as "example'. Then you can loop around based on the length of x.

https://www.w3schools.com/jsref/met_document_getelementsbyclassname.asp
try this:
var input = document.forms[0].querySelectorAll('input[type=text]');
var result = Array.from(input).reduce((r, ele) => {
r[ele.name] = ele.value;
return r;
}, {});
console.log(result);
<form name="form1">
<input type="text" name="value1" value=1>
<input type="text" name="value2" value=2>
<input type="text" name="value3" value=3>
<input type="text" name="value4" value=4>
<input type="button" id="save" onclick="fc1()" value="Save">
</form>
If you used something like .. I think it will work. :)
var myObj = {};
var elems = document.getElementsByTagName('input'), i;
for (i in elems) {
myObj[value + i] = myObj[i].value;
}
return from getElementsByTagName is an array of all matching tags. there are some wizard answers in here ha. :)
document.querySelectorAll is made for this.
document.querySelectorAll("form[name='form1'] input[type='text']")
will return all input fields of type text in form1 as HTML nodes.
let elements = document.querySelectorAll("form[name='form1'] input[type='text']");
elements.forEach(e => console.log(e.value));
...logs the values of the input fields. Don't make things harder on yourself by hard coding classes or ID's, and this will allow you to target the input elements you need without additional checks or without fetching every input on the page.
Example:
const values = {};
document.querySelectorAll("form[name='form1'] input[type='text']").forEach(element => values[element.name] = element.value);
console.log(values);
<form name="form1">
<input type="text" name="value1" value=1>
<input type="text" name="value2" value=2>
<input type="text" name="value3" value=3>
<input type="text" name="value4" value=4>
<input type="button" id="save" onclick="fc1()" value="Save">
</form>
This is an alternative solution done with jQuery.
Hope this is what you were looking for. Happy to explain or help in a better solution if needed.
//jQuery solution
const obj = {}
$('#save').click(function(e){
var form = $(this).parent();
var inputs = form.children().not(':input[type=button]');
$.each( inputs, function(){
obj[$(this).attr('name')] = $(this).val();
});
console.log(obj);
})

I try to pass the textbox value from a page to another page.
I try to pass that text box but failed I use javascript for doing that.
I have to try to change my code properly but still not work
the error is the data that passing to the text box is multiple.
this is my code
1st-page code
function myFunction() {
var inputTest = document.getElementById('tanggal2').value;
var inputTest1 = document.getElementById('dt').value;
localStorage.setItem( 'objectToPass', inputTest );
localStorage.setItem( 'objectToPass1', inputTest1 );
if (inputTest=="") {
window.open('report_pengambilan_singgle.html','','height=650,width=1200');
}
else {
window.open('report_pengambilan_singgle1.html','','height=650,width=1200');
}
}
<input type="text" id="dt" type="text" name="dt" maxlength="1" size="23" readonly="readonly" style="visibility:hidden" />
<input type="text" id="tanggal2" type="text" name="tanggal2" maxlength="1" size="23" readonly="readonly" style="visibility:hidden" />
<label onclick="myFunction();" >a</label>
and this my 2nd-page code
var inputTest = localStorage.getItem('objectToPass');
var inputTest1 = localStorage.getItem('objectToPass1');
var displayData = inputTest;
var displayData = inputTest1;
document.getElementById("datepicker1").value=inputTest;
document.getElementById("datepicker2").value=inputTest;
document.getElementById("datepicker3").value=inputTest;
localStorage.removeItem( 'objectToPass1' ); // Clear the localStorage
localStorage.removeItem( 'objectToPass' ); // Clear the localStorage
Try this way...
test.html
<script>function myFunction() {
var inputTest = document.getElementById('tanggal2').value;
var inputTest1 = document.getElementById('dt').value;
if (inputTest=="") {
window.open('report_pengambilan_singgle.html','','height=650,width=1200');
}
else {
window.open('test1.html?name=' + inputTest1,'','height=650,width=1200');
}
}
</script>
<input type="text" id="dt" type="text" name="dt" size="23" />
<input type="text" id="tanggal2" type="text" name="tanggal2" size="23" />
<button onclick="myFunction();" >a</button>
test1.html
<script>window.onload = function () {
var url = document.location.href,
params = url.split('?')[1].split('&'),
data = {}, tmp;
for (var i = 0, l = params.length; i < l; i++) {
tmp = params[i].split('=');
data[tmp[0]] = tmp[1];
}
document.getElementById("datepicker1").value = data.name;
}
</script>
<input type="text" id="datepicker1" type="text" name="datepicker1" size="23" />
i Hope working for u...
you have textbox which have hidden and not any value define
so first set any value in textbox and create textbox in another page before your <script> start
like
<input type="text" id="datepicker1" value="">
<input type="text" id="datepicker2" value="">
<input type="text" id="datepicker3" value="">
I have 3 textboxs.Their names and ids are different.I can merge their values with their names or ids but I need to merge their values with type. How can I do it.
<input type="text" id="txt1" name="textbox1">
<input type="text" id="txt2" name="textbox2">
<input type="text" id="txt3" name="textbox3">
You can get all the textbox elements by their type using document.querySelectorAll("input[type=text]").
If by merge you mean concatenating the values.
var textBoxes= document.querySelectorAll("input[type=text]");
var mergedValue;
for(var i=0;i<textBoxes.length;i++)
{
mergedValue+=textBoxes[i].value;
}
var dataVal=document.querySelectorAll('[type=text]');
var myVal="";
dataVal.forEach(function(entry) {
myVal+=entry.value;
});
console.log(myVal);
<input type="text" id="txt1" name="textbox1" value="2">
<input type="text" id="txt2" name="textbox2" value="2">
<input type="text" id="txt3" name="textbox3" value="2">
Here is another possible solution.
function mergeData() {
var textboxes = document.getElementsByTagName("input");
var mergedText = "";
for (var i = 0; i < textboxes.length; i++) {
if (textboxes[i].type === "text" ) {
mergedText = mergedText + textboxes[i].value;
}
}
document.getElementById("merged").innerHTML = mergedText;
}
<input type="text" id="txt1" name="textbox1">
<input type="text" id="txt2" name="textbox2">
<input type="text" id="txt3" name="textbox3">
<button onclick="mergeData()">Merge</button>
<div id="merged"></div>
So i have a dynamic input field came from append with different class name and names, i want to check each of input field value already exist or duplicate.
This would look like
The first criteria_name is default and the others are appendend.
<input type="text" name="criteria_name" class="criteria_name">
<input type="text" name="criteria_name2" class="criteria_name2">
<input type="text" name="criteria_name3" class="criteria_name3">
<input type="text" name="criteria_name4" class="criteria_name4">
<input type="text" name="criteria_name5" class="criteria_name5">
I am trying to check each one of those if there is no duplicated else proceed.
var critname_arr = [];
var input_check;
var crit_name_of_first = $('input.criteriaNames').val();
var acappended = append_crit_header+1;
var count_to = 0;
for(var ab = 2; ab<=acappended; ab++){
var crit_arr;
if(crit_name_of_first == $('input.criteria_each_name'+ab+'').val()){
alert("Criteria cannot be duplicate");
return false;
}else{
input_check = $('input.criteria_each_name'+ab);
input_check.each(function(){
crit_arr = $.trim($(this).val());
});
critname_arr.push(crit_arr);
}
if($('input.criteria_each_name'+ab+'').val() == critname_arr[count_to]){
alert('criteria cannot be duplicate');
return false;
}
count_to++;
}
console.log(critname_arr);
Here is just an example of how you can do it. In the fiddle change one of the values to one that is already in another field (make a duplicate value) to see it do something. If there are no duplicates, it will not do anything. Click the "Button" text to run the duplicate check:
jsFiddle: https://jsfiddle.net/o52gjj0u/
<script>
$(document).ready(function(){
$('.ter').click(function(e) {
var stored = [];
var inputs = $('.criteria_name');
$.each(inputs,function(k,v){
var getVal = $(v).val();
if(stored.indexOf(getVal) != -1)
$(v).fadeOut();
else
stored.push($(v).val());
});
});
});
</script>
<!-- Just use an array name for the input name and same class name as well -->
<div class="ter">Button</div>
<input type="text" name="criteria_name[]" class="criteria_name" value="1" />
<input type="text" name="criteria_name[]" class="criteria_name" value="2" />
<input type="text" name="criteria_name[]" class="criteria_name" value="3" />
<input type="text" name="criteria_name[]" class="criteria_name" value="4" />
<input type="text" name="criteria_name[]" class="criteria_name" value="5" />
I am running this code and it returns me set of values which are checked
var a = [];
var cboxes = $('input[name="suppcheck[]"]:checked');
var len = cboxes.length;
for (var i=0; i<len; i++) {
a[i] = cboxes[i].value;
//document.getElementByName('suppgrp[]').value = a[i];
}
I have a hidden field with ID suppgrp where I want to push all these values retrieved and wanted to pass it in array..
But I am not able to...where am I going wrong?
i have added some extra code which when page load then will call this function and also when change checkbox value then also call this function so all time it will work
loadCheck(); // initial call this function to load data
$('input[type="checkbox"]').change(function()
{
loadCheck();
});
function loadCheck() {
$('#hiddenValue').val('');
$('#showValue').val('');
var checkboxes = $('input[name="suppcheck[]"]:checked');
var data = [];
var len = checkboxes.length;
for (var i=0; i<len; i++) {
data[i] = checkboxes[i].value;
}
$('#hiddenValue').val(data);
$('#showValue').val(data);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

var a = [];
jQuery('input[type="checkbox"]').change(function()
{
var cboxes = jQuery('input[name="suppcheck[]"]:checked');

var alval = '';

if (alval != '') {
