Hello I can't set min and maximum value from database.
Actually I want to make dynamic it through PHP. In the back-end there should be two fields first minimum and second one with maximum. In maximum field, I can set maximum and in minimum field I can set, and call it through PHP in my coding.
Is that something can we do? here's coding.
<html>
<body>
<head>
</head>
<?php
echo '
<script>
$(document).on("change", ".qty1", function() {
var sum = 0;
$(".qty1").each(function(){
sum += +$(this).val();
});
$(".total").val(sum);
});
</script>';
$maxnum = 7;
if(num > $maxnum){
echo "<script>alert('Yes it is big');</script>";
}
?>
<input type="text" class="qty1" value="" />
<input type="text" class="qty1" value="" />
<input type="text" class="qty1" value="" />
<input type="text" class="qty1" value="" />
<input type="text" class="qty1" value="" />
<input type="text" class="qty1" value="" />
<input type="text" class="total" value="" />
</body></html>
how can I use php with jquery or should I change my coding. I don't know how I can change my coding is there any idea please?
you could put all values into an array and then get the min/max
$(document).on("change", ".qty1", function() {
var arr = [];
var sum = 0;
$(".qty1").each(function(){
arr.push($(this).val());
sum += +$(this).val();
});
$(".total").val(sum);
$("#min").val(Math.min.apply(Math, arr));
$("#max").val(Math.max.apply(Math, arr));
});

I have multiple inputs and i want to display result in input and change it freely.
When i type 5 in first input it should display 5 in the second. But how to change the value of second input and display it in the first? I want to be able to constantly change the values.
function calc(){
var val1 = document.getElementById("val1");
let val2 = document.getElementById("value2");
val2.value = 2;
}
<html>
<head>
</head>
<body>
<input id="value1" type="number" value="" oninput="calc()">
<input id="value2" type="number" value="" oninput="calc()">
</body>
</html>
You can pass an additional parameter to your function and change the values as per the parameters.
function calc(num){
var val1 = document.getElementById("value1");
let val2 = document.getElementById("value2");
num ? val1.value = val2.value : val2.value = val1.value;
}
<input id="value1" type="number" value="" oninput="calc(0)">
<input id="value2" type="number" value="" oninput="calc(1)">
I have replaced the if else condition with a ternary operator. I hope that you are familiar with it.
<html>
<head>
</head>
<body>
<input id="value1" type="number" value="" oninput="document.getElementById('value2').value =this.value">
<input id="value2" type="number" value="" oninput="document.getElementById('value1').value =this.value">
</body>
</html>
Use like this
I want to know how to calculate the input values of the following fields
<input type="text" name="score1" class="auto-sum">
<input type="text" name="score2" class="auto-sum">
<input type="text" name="score3" class="auto-sum">
And update the span text and the hidden field value
TOTAL <span id="amountTotal">0 </span>
<input id="total" type="hidden" name="total" value="">
Thanks in advance
This should do what you want to achieve:
function displaySum () {
var sum = 0;
// iterate over the input fields
$('.auto-sum').each(function () {
var value = $(this).val() || 0;
var number = parseInt(value, 10); // parse the input value to an integer
if (isNaN(number)) {
number = 0;
}
sum += number; // add the value to the sum
});
// set the value of the two elements
$('#amountTotal').text(sum);
$('#total').val(sum);
}
// whenever the value of one of the input fields changes, call the displaySum function
$('.auto-sum').on('change, keyup', displaySum);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" name="score1" class="auto-sum">
<input type="text" name="score2" class="auto-sum">
<input type="text" name="score3" class="auto-sum">
TOTAL <span id="amountTotal">0 </span>
<input id="total" type="hidden" name="total" value="">
I tried with blur method for after mouseleave from input and check all input values and added ! Then update to wanted element !!
$("input").on("blur",function(){
var total = 0;
$("[type='text']").each(function(){
if($(this).val() != "") {
total += parseInt($(this).val());
}
});
$("#amountTotal").text(total);
$("#total").val(total);
});
Try with query each() function .Use with parseFloat convert the string to number .for real time update do with keyup event
$('.auto-sum').keyup(function(){
var a=0;
$('.auto-sum').each(function(){
a+=parseFloat($(this).val())
})
$('#amountTotal').text(a|0)
$('#total').val(a|0)
console.log($('#total')[0].outerHTML)//its show the hidden field value
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" name="score1" class="auto-sum" value="2" >
<input type="text" name="score2" class="auto-sum" value="5">
<input type="text" name="score3" class="auto-sum" value="5">
TOTAL <span id="amountTotal" >0 </span>
<input id="total" type="hidden" name="total" value="">
You can use <input type="number" /> inputs to force values entered to be a number.
From there you can call jQuery with the query selector input.auto-sum to get all of the input elements with the class auto-sum
Using the each function you can add the numeric to an accumulator to get the total.
You can then use jQuery with the query selectors needed to set any other elements on the page with the Total value.
function getTotal() {
var total=0;
$('input.auto-sum').each(function(i,e)
{
total += Number($(e).val());
});
$('#amountTotal').text(total);
$('#total').val(total);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
Score 1: <input type="number" name="score1" class="auto-sum"><br />
Score 2: <input type="number" name="score2" class="auto-sum"><br />
Score 3: <input type="number" name="score3" class="auto-sum"><br />
TOTAL: <span id="amountTotal">0 </span><br />
<input id="total" type="hidden" name="total" value="">
<input type="button" id="btnTotal" onclick="getTotal()" value="Get Total" />
Please try this one.
$('.auto-sum').on('change',function(){
var totalvalue=0;
$('.auto-sum').each(function(a,b){
totalvalue=totalvalue+parseInt(($(b).val()=='' || isNaN($(b).val()))?0:$(b).val());
});
$('#amountTotal').text(totalvalue);
$('#total').val(totalvalue);
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" name="score1" class="auto-sum">
<input type="text" name="score2" class="auto-sum">
<input type="text" name="score3" class="auto-sum">
TOTAL <span id="amountTotal">0</span>
<input id="total" type="hidden" name="total" value="">
<input type="text" name="score1" class="auto-sum">
<input type="text" name="score2" class="auto-sum">
<input type="text" name="score3" class="auto-sum">
<input type="button" id="calculator" value="Caculate">
$("#calculator").on("click",function (){
var result=0;
var sum_fields=$(".auto-sum");
for(var i=0;i<sum_fields.length;i++){
if(!isNaN(sum_fields[i]) && sum_fields[i]>0){
result += sum_fields[i];
}
}
$("#amountTotal").text(result);
$("#total").val(result);
});
Create array for the fields and loop through them
Check if it not a NaN and more than 0 add them to the result then after the loop attach the result to the hidden field and as a span text
I post this as an answer because the comment areas are to small
At first i think it´s an good idea to write
<input type = "number">
when you don´t want to display the small arrows look at this solution:
https://css-tricks.com/snippets/css/turn-off-number-input-spinners/
the keyup event ist the best way to "live" display the total sum
At last take a look at vue.js
This is the best solution for this scenario.
if you're interested in a pure javascript solution:
All inputs have an oninput event attribute that fires when the input is changed.
You can attach an event handler to the event like so:
<input oninput="updateTotal" />
where updateTotal is a function declared in your script:
function updateTotal { /* code that updates the total */ }
OR if you select the input in your script then you can attach the event handler like this:
selectedInput.oninput = function updateTotal () {
...
}
Here's my implementation that selects all the inputs with the class "auto-sum", assigns the event handler to each of them and updates the code by looping over each input's value attribute:
https://jsfiddle.net/billy_reilly/5dd24v81/2/
function displaySum () {
var sum = 0;
// iterate over the input fields
$('.auto-sum').each(function () {
var value = $(this).val() || 0;
var number = parseInt(value, 10); // parse the input value to an integer
if (isNaN(number)) {
number = 0;
}
sum += number; // add the value to the sum
});
// set the value of the two elements
$('#amountTotal').text(sum);
$('#total').val(sum);
}
// whenever the value of one of the input fields changes, call the displaySum function
$('.auto-sum').on('change, keyup', displaySum);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" name="score1" class="auto-sum">
<input type="text" name="score2" class="auto-sum">
<input type="text" name="score3" class="auto-sum">
TOTAL <span id="amountTotal">0 </span>
<input id="total" type="hidden" name="total" value="">
I'm using spring mvc for my form which has the tag
<form:input type="number" class="value1" id="value1" path="commandName.object.field1" />
<form:input type="number" class="value1" id="value1" path="commandName.object.field2" />
<input type="text" disabled="disabled" id="result" />
I read some questions in regards to calculations and even found a js fiddle:
http://jsfiddle.net/g7zz6/1125/
how do i calculate 2 input fields and put results in 3rd input field
but it doesn't work when the input tag is form:input. Is it possible to do auto calculation of the 2 form:input fields upon keyin and update the 3rd input?
Here you go
HTML
<input type="text" class="input value1">
<input type="text" class="input value2 ">
<input type="text" disabled="disabled" id="result">
JS
$(document).ready(function(){
$('input[type="text"]').keyup(function () {
var val1 = parseInt($('.value1').val());
var val2 = parseInt($('.value2').val());
var sum = val1+val2;
$("input#result").val(sum);
});
});
Fiddle https://jsfiddle.net/1sbvfzcc/
$(document).ready(function(){
var val1 = +$(".value1").val();
var val2 = +$(".value2").val();
$("#result").val(val1+val2);
});
$('.input').blur(function(){
var val1 = +$(".value1").val();
var val2 = +$(".value2").val();
$("#result").val(val1+val2);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" class="input value1" value="20">
<input type="text" class="input value2" value="30">
<input type="text" disabled="disabled" id="result">
Please check the code this might help you understand why your code is not working.
You are using document ready function which is not able to get the value as no default value for input box.
I have added a new blur function which will calculate the value on change of input box
Try this your form tag syntax was wrong
$('form').on('keyup' ,'.value1', function(){
var k=0;
$('.value1').each(function(){
k +=parseFloat($(this).val()|0);
})
$('input:text').val(k)
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form>
<input type="number" class="value1" id="value1" path="commandName.object.field1" />
</form>
<form>
<input type="number" class="value1" id="value1" path="commandName.object.field2" />
</form>
<input type="text" disabled="disabled" id="result" />
jQuery, disable all others input on same class if sum of all value more than x
How to disable "HTML input box" which not empty node when the sum of any input box has value. I want to calculate some of any input field and disable any others if the sum is greater than x.
For example to this code:
second field = 5
forth field = 10,
sum is 15
first field and third field should be disabled
$('.inputReward').on('input',function() {
//$(this).next().not(this).prop('disabled', this.value.length)
var sum=0;
$('.inputReward').each(function () {
sum += +$(this).val();
if(sum>15) //15 is maximum value
$(this).next().not(this).prop('disabled', true);
else
$(this).next().not(this).prop('disabled', false);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="number" name="sRewards" value="" class="inputReward" />
<input type="number" name="sReward1" value="" class="inputReward" />
<input type="number" name="sReward2" value="" class="inputReward" />
<input type="number" name="sReward3" value="" class="inputReward" />
But now i just can do only disable all next input field of a last not empty node.
I think this is my best solution :)
$('.inputReward').on('input',function() {
//$(this).next().not(this).prop('disabled', this.value.length)
var sum=0;
$('.inputReward').each(function () {
sum += +$(this).val();
});
if(sum>=15)
$(this).siblings().not(this).prop('disabled', true);
else
$(this).siblings().not(this).prop('disabled', false);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="number" name="sRewards" value="" class="inputReward" />
<input type="number" name="sReward1" value="" class="inputReward" />
<input type="number" name="sReward2" value="" class="inputReward" />
<input type="number" name="sReward3" value="" class="inputReward" />
I need the total of all the values from my input. The result must be displayed in the input field total that is readonly.
The user can enter 1 or more values. The problem is that my var value is not correct. I'd also like to know how I can return the value immediately by onchange?
$(document).ready(function() {
$("div#example input").change(function() {
var value = '';
$("div#example input[name!=total]").each(function() {
value += $(this).val();
});
console.log("value after each: " + value);
});
})
HTML:
<div id="example">
<input type="text" size="5" id="value1" name="value1" />
<input type="text" size="5" id="value2" name="value2" />
<input type="text" size="5" id="value3" name="value3" />
<input type="text" size="5" id="value4" name="value4" />
<input type="text" size="5" id="value5" name="value5" />
<input type="text" size="5" id="total" readonly="readonly" class="bckground" name="total" />
Try something like this:
$(document).ready(function() {
$("div#example id^='value'").change(function() {
var value = 0;
$("div#example input[name!=total]").each(function() {
var i = parseInt($(this).val());
if (!isNaN(i))
{
value += i;
}
});
$('#total').val(value);
});
})
use += parseInt($(this).val());
var sum = 0;
$('input[id^=value]').each (function(){ sum+=$(this).val(); });
$('#total').val( sum );
:]
I think this might be closer:
<script type="text/javascript">
$(document).ready(function() {
$("#example value").change(function() {
var total = 0;
$("#example value").each(function() {
total += parseInt($(this).val());
});
window.console && console.log("value after each: " + total);
});
})
</script>
<div id="example">
<input type="text" size="5" class="value" name="value1" />
<input type="text" size="5" class="value" name="value2" />
<input type="text" size="5" class="value" name="value3" />
<input type="text" size="5" class="value" name="value4" />
<input type="text" size="5" class="value" name="value5" />
<input type="text" size="5" id="total" readonly="readonly" class="bckground" name="total" />
</div>
Your original selector for $.change() was including the total box, which I suspect you don't want.
Am I correct in guessing you want to add numbers? Your original 'value' variable was a string.
And BTW, it's safer to use the 'window.console && console.log' idiom, since there won't be a console variable for many users. (Though I bet that line was only there for debugging.)
EDIT
Added parseInt() based on other suggestions.
Use the jQuery form serialization:
alert($("form_id").serialize());
There is also a comparison for different serialization types: http://jquery.malsup.com/form/comp/
