How is repeated code HTML for five times?
like repeated(echo) a input <input type="text" name="ok"> with a js code five times.
I mean this is that, a input by a js code echo five times
I want after run jQuery code output is this (5 input):
<input type="text" name="ok">
<input type="text" name="ok">
<input type="text" name="ok">
<input type="text" name="ok">
<input type="text" name="ok">
how is it?
Your question isn't totally clear, do you mean this?
for (var i = 0; i<5;i++) {
$("body").append("<input type='text' name='ok'>");
}
function EchoInput(html, count) {
var result = [];
for (var i = 0; i < count; i++)
result.push(html);
return result.join("");
}
To use this function, you could do something like this:
document.write(EchoInput("<input type='text' name='ok'>", 5));
var body = $('body');
for(var i = 0; i < 5; i++) {
body.append('<input type="text" name="ok">');
}

Instead of creating HTML, you can create elements directly.
Here is a way that let you set different names on each input field. Right now all five have the name "ok", but you can change that in the array:
// use ready event so that the page is loaded:
$(document).ready(function(){
// decide where to add the elements:
var container = $('body');
// loop over an array of names:
$.each(['ok','ok','ok','ok','ok'], function(idx, name) {
// create an element and add to the container:
container.append($('<input/>', { type: "text", name: name }));
});
});

I've recently become familiar with Jquery selectors....and they work great. Starts with...ends with....
The problem I have currently is that all of my variable names essentially start with similar patterns and end with similar patterns. This ID is generated from somewhere else so I'm hoping I can do something to use it effectively.
The pattern ID format essentially looks like...
"#id_newbudgetlineitem_set-0-line_item_october"
"#id_newbudgetlineitem_set-0-line_item_november"
"#id_newbudgetlineitem_set-0-line_item_december"
I want to essentially matching on the set-* but only if it's identical to the other ids in my array. Is this even possible without having to hard code anywhere from set-0 to set-1000? Unfortunately the class for each one is the same as is the name situation. Is there someway to say if the set numbers all match in a given array then add them up? I can't use starts with or ends with in this case...and don't want to hardcode 1000 possibilities. Thanks in advance for any ideas or thoughts.
I am trying to do something like.....
function update_total()
{
var total = 0;
$('.budget').each(function(index, element) {
"#id_newbudgetlineitem_set-0-line_item_october" +
"#id_newbudgetlineitem_set-0-line_item_november" +
"#id_newbudgetlineitem_set-0-line_item_december"
var val = parseFloat($(element).val());
if( !isNaN( val )){
total += val;
}
});
$("#id_total").val(total);
}
Here's a working solution........
function update_total_total_total()
{
var ret = +$("input[name$='set-0-line_item_january']").val() + +$("input[name$='set-0-line_item_february']").val() + +$("input[name$='set-0-line_item_march']").val() + +$("input[name$='set-0-line_item_april']").val() + +$("input[name$='set-0-line_item_may']").val() + +$("input[name$='set-0-line_item_june']").val() + +$("input[name$='set-0-line_item_july']").val() + +$("input[name$='set-0-line_item_august']").val() + +$("input[name$='set-0-line_item_september']").val() + +$("input[name$='set-0-line_item_october']").val() + +$("input[name$='set-0-line_item_november']").val() + +$("input[name$='set-0-line_item_december']").val();
$("input[name$='set-0-line_item_total']").val(ret);
}
But I could have up to 1000 different set values. Is there some other way to do this without having to hard code this 999 more times?
This is a lot closer....but total still says 0. It's updating all of the totals to 0...so that's progress but not getting the actual totals. Forward progress thanks to Swati.
function update_total_total_total() {
//get length of input line_total for each sets..
for (var i = 0; i < $("[name$=line_item_total]").length; i++) {
var total = 0;
//get all inputs but not line_item _total
$(`input[name*=id_newbudgetlineitem_set-${i}-line_item]:not([name$=line_item_total]):not([name$=line_item_cost_center]):not([name$=line_item_description])`).each(function(index, element) {
var val = parseFloat($(element).val());
if( !isNaN( val )){
total += val;
}
})
$(`input[id$=set-${i}-line_item_total]`).val(total); //set value..of input
}
}
You can get length of total input whose name ends with line_item_total so this value will be counter for for-loop.
Then , inside for loop you can use $(`input[name*=id_newbudgetlineitem_set-${i}-line_item]:not([name$=line_item_total])`) this will fetch values from all inputs expect the line_total_item then add value on each iteration .
Lastly , use $(`input[name$=set-${i}-line_item_total]`).val(total); to set total inside line_total_item textbox.
Demo Code :
function update_total_total_total() {
//get length of input line_total for each sets..
for (var i = 0; i < $("[name$=line_item_total]").length; i++) {
var total = 0;
//get all inputs but not line_item _total
$(`input[name*=id_newbudgetlineitem_set-${i}-line_item]:not([name$=line_item_total]):not([name$=line_item_cost_center]):not([name$=line_item_description])`).each(function(i, element) {
var val = parseFloat($(element).val());
if (!isNaN(val)) {
total += val;
}
})
$(`input[name$=set-${i}-line_item_total]`).val(total); //set value..of input
}
}
update_total_total_total()
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

This was the final working code. As Swati suggested it was an incorrect name reference.
function update_total_total_total() {
for (var i = 0; i < $("[name$=line_item_total]").length; i++) {
var total = 0;
$(`input[name*=newbudgetlineitem_set-${i}-line_item]:not([name$=line_item_total]):not([name$=line_item_cost_center]):not([name$=line_item_description])`).each(function(i, element) {
var val = parseFloat($(element).val());
if( !isNaN( val )){
total += val;
}
})
$(`input[name$=set-${i}-line_item_total]`).val(total);
}
}
Im trying to create a list of input ID's and use it in array, to make them readOnly - but the result is error -> "cannot read property 'readOnly' of null".
Can you give me a hint what I should change?
script language="javascript" type="text/javascript">
$(document).ready(function () {
$(function(){
var index, len;
$.get('/SomeList.txt', function(data){
var SomeList = data.split('\n');
for (index = 0, len = SomeList.length; index < len; index++) {
document.getElementById(SomeList[index]).readOnly = true;
}
});
});
});
</script>
and txt file contains name of input ID:
TextFieldName
TextFieldEmail
TextFieldDepartment
TextFieldOffice
Assuming you have some elements with the given IDs you must check if the element exists first before doing
document.getElementById(SomeList[index]).readOnly = true;
so replace that line with
var myElement = document.getElementById(SomeList[index]);
if(myElement == null) {
return;
}
myElement.readOnly = true;
That should work like following example where the IDs come from an array and the second one will not mach because of xxxxx so it's not readonly. But all the others are.
var dataArray = [
'TextFieldName',
'TextFieldEmailxxxxx',
'TextFieldDepartment',
'TextFieldOffice'
];
dataArray.forEach(function(id){
var myElement = document.getElementById(id);
if(myElement == null) {
return;
}
myElement.readOnly = true;
});
<input id="TextFieldName" type="text">
<input id="TextFieldEmail" type="text">
<input id="TextFieldDepartment" type="text">
<input id="TextFieldOffice" type="text">
var id_array=["email","country"];
for (i = 0; i <id_array.length; i++) {
document.getElementById(id_array[i]).readOnly = true;
}
Email: <input type="text" id="email" value="test#mail.com"><br>
Country: <input type="text" id="country" value="Norway" >
it is working fine in my case.
i think there may be whitespace in your array items because your are reading them from file.so try to trim array items.
and make sure you assign id's to input elements
I have a automatically rendered HTML form which uses a index for the input fields.
for quantity:
<input id="id_orderline_set-0-orderline_quantity" name="orderline_set-0-orderline_quantity" onkeyup="orderlineTotal()" type="number" value="120">
for product price;
<input id="id_orderline_set-0-orderline_product_price" name="orderline_set-0-orderline_product_price" onkeyup="orderlineTotal()" type="number" value="22">
for total line price;
<input id="id_orderline_set-0-orderline_total_price" name="orderline_set-0-orderline_total_price" tag="orderline_total_price" type="number" value="2640">
For the following lines the index of the id and name are increased, only quantity example shown;
<input id="id_orderline_set-1-orderline_quantity" name="orderline_set-1-orderline_quantity" onkeyup="orderlineTotal()" type="number" value="55">
I would like to use the following JavaScript to calculate the total line price;
function orderlineTotal()
{
var orderlineTotalPrice = 0;
var theForm = document.forms["orderform"];
var orderlineQuantityField = theForm.getElementsByName["orderline_quantity"];
var orderlineProductPriceField = theForm.getElementsByName["orderline_product_price"];
var orderlineTotalPriceField = theForm.getElementsByName["orderline_total_price"];
for (var i = 0; i < orderlineQuantityField.length; i ++) {
orderlineTotalPrice = orderlineQuantityField[i].value * orderlineProductPriceField[i].value;
orderlineTotalPriceField[i].value = orderlineTotalPrice;
}
}
Offcourse this wont work because the name of the elements do not match. Can i lookup the name of the element by using a partial name? If not, how should i loop through the input boxes to calculate the line total?
You tagged jQuery so if you want to use jQuery you can use ends with selector:
$("input[name$='orderline_quantity']")
ends with
there's also
starts with
$("input[name^='id_orderline_set-0']")
and contains
$("input[name*='orderline_']")
Maybe you could use static names. Set the equal input names for inputs of the same type and then use this function:
var elements = document.getElementsByName('name');
for (var i=0; i<elements.length; i++) {
doSomething(elements[i]);
}
where name matches name of input.
Example
Instead of:
name="orderline_set-0-orderline_total_price"
use:
name="orderline_total_price"
and then:
var orderlineTotalPriceField = theForm.getElementsByName["orderline_total_price"];
and so on...
I have a table in my jsp:
<table id="table">
<tr>
<th>Valor</th>
<th>Recompensa</th>
</tr>
<tr>
<td>
<input type="text" name="amount">
</td>
<td>
<input type="text" name="text">
</td>
</tr>
</table>
<input type="button" value="Send" onclick="send('table')"/>
I write something in the boxes, and press Send, and the send Javascript method is called.
Javascript send method, which iterates through rows and cells, and stores the values in an Array:
function send(tableID) {
var table = document.getElementById(tableID);
var array= new Array();
for (var i = 1;i<table.rows.length; i++){
var row = table.rows[i];
for (var j = 0;row.cells.length; j++){
alert("added to array: "+row.cells[j].innerHTML);
array.push(row.cells[j].innerHTML);
}
}
}
I am getting "<input name="amount" type="text">" in the alert. I have tried using row.cells[j].firstChild.innerHTML, receiving undefined.
What am I doing wrong? how could I get what the user writes in the textboxes?
PS: I'm using Firefox to test. Maybe a browser issue?
You can use:
alert("added to array: " + row.cells[j].getElementsByTagName('INPUT')[0].value);
jsFiddle Example: http://jsfiddle.net/4TjYH/
EDIT: By the way, the code you posted may have been stripped down for simplicity, but if it's your actual code you can really simplify it:
function send(tableID) {
var array = new Array(),
inputs = document.getElementById(tableID).getElementsByTagName('INPUT');
for (var i = 0; i < inputs.length; i++){
alert("added to array: " + inputs[i].value);
array.push(inputs[i].value);
}
}
In the second loop is an error:
for (var j = 0; j < row.cells.length; j++){
"j <" was missing. the same problem was in the answer of Gavin: here the edit fiddle: http://jsfiddle.net/h693g/2/
Well, if you just want what the user has typed in the textboxes, you can assign ids to each textbox and use getElementById():
<input type="text" name="amount" id="amount">
<input type="text" name="text" id="text">
var amount = document.getElementById("amount");
var text = document.getElementById("text");
Then just push those two values on your array:
array.push(amount.value);
array.push(text.value);
You can put this logic in a loop, looping through an array of element ids or something if you didn't want to write similar code over and over.
in my process text filed in array i need to get the value via javascript but my code is not working my code following
<input type="text" id="itemid[]" name="itemid[]" class="span12"/>
and javascript code is
function getstock()
{
var itemidarr=document.getElementById('itemid[]');
if(itemidarr!= null)
{
alert(itemidarr.length);
}
}
any other solution for this
The IDs can't contain brackets, these: [], so:
<input type="text" id="itemid1" name="itemname1" class="span12"/>
<input type="text" id="itemid2" name="itemname1" class="span12"/>
<input type="text" id="itemid3" name="itemname1" class="span12"/>
Then you have to loop through the IDs:
function getstock()
{
for(var i=1; i<=3; i++){
var itemidarr=document.getElementById("itemid"+i);
if(itemidarr!= null) alert(itemidarr.length);
}
}
The id attribute here cannot contain [ ].
Put your textboxex in "fieldset tag"
Like:
<fieldset id="field">
//Put you text boxes here<input type='text'>
</fieldset>
Access these by:
document.getElementById("list....").getElementsByTagName("input")[indexoftext];
indexoftext is the text box you wan to choose.
Hope it helps!
you can try something like this below
<input type="text" id="itemid" name="itemid" class="span12"/>
function getstock()
{
var itemidarr = document.getElementsByName('itemid');
for(var i = 0; i < itemidarr.length; i++){
var item=document.getElementsByName('itemid')[i].value;
if(item!= null)
{
alert(item);
}
}
}
You can't make an array to fill in an input text, only for input like radio or checkbox.
Text input only accept a single string.
function getstock() {
var a = [];
jQuery.each(this, function(i, field){
a.push($.trim(field.value));
});
return a;
}
can u use this code
i got the result
function getstock1()
{
alert("test");
var itemidarr = document.getElementsByName('itemid[]');
for (var i = 0; i < itemidarr.length; i++)
{
alert(itemidarr[i].value);
}
