It should not be possible to enter a sequence of numbers with more than 7 digits, these having spaces or not between the characters.
Example number sequences to block:
99999999999
99 9 9999 9999
99 9999 9999
<input type="text" name="texto" id="texto"/>
$('input:text, textarea').keyup(function(){
var num = $(this).val();
var a1 = num.split(" ");
for (i=0;i<a1.length;i++)
{
var total_letras = a1[i].length;
if($.isNumeric(a1[i])){
if(total_letras > 7)
{
$(this).val( num.substring(0, num.length - 2) );
$(this).addClass("input_bloqueado");
}
else
{
$(this).removeClass("input_bloqueado");
}
}
}
});
That is, if the user enters a sequence of numbers longer than 7 digits, the script must obfuscate or remove these numbers.
You can try this regex /((?:[1-9]\s*){7})/g or /((?:\d\s*){7})/g if you want the number from 0-9.
Demo:
$('#texto').keyup(function(){
var reg = /((?:[1-9]\s*){7})/g;
var texto = $(this).val();
var result = texto.replace(reg,"********") ;
$("#texto").val( result );
});

I have one form with textbox and user needs to insert width X height format value so I need to validate whether it is in correct format or not using JavaScript regexp validations.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<input type="text" name="txt" class="txt_val" value=""/>
<input type="submit" class="clk" value="submit"/>
<script>
$(".clk").click(function(){
var number=$(".txt_val").val();
var compare=/[0-9]{2}^[a-z .x-]{1}[0-9]{2}/;
if(number.match(compare)){
alert('match');
}
else{
alert('not match');
}
});
</script>
Expected output with cases:
1) format should be like this
10X10 or 23X24 or 36X24 or 44X56
like any width by height with uppercase or lowercase 'x'
2) any number with two digits following widthXheight and charecter 'x' can be upper case or lower case
Your regex should be /[0-9]{2}[x|X][0-9]{2}$/
Where:
[0-9] - Matches number in the range between 0 (index 48) and 9 (index 57)
{2} - Quantifier — Matches exactly 2 times
[x|X] - Match the character x or X
$ - Asserts position at the end of a line
$(".clk").click(function(){
var number=$(".txt_val").val();
var compare=/[0-9]{2}[x|X][0-9]{2}$/;
if(number.match(compare)){
alert('match');
}
else{
alert('not match');
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<input type="text" name="txt" class="txt_val" value=""/>
<input type="button" class="clk" value="submit"/>

In my project, there is a text box to enter the password and the password characters limit is up to 15. So, I want to display an alert message through javascript as soon as the user tries to enter the 16th character. Please help!
Try this.
function alrtMsg() {
var x = document.getElementById("pwd").value;
if(x.length > 16){
alert("maximum length is 16");
document.getElementById("pwd").value = '';
}
}
<html>
<body>
<input type="password" id="pwd" onkeyup="alrtMsg()">
</body>
</html>
Try this on Javascript:
document.getElementById("password").onkeyup = function() {
var text = document.getElementById("password").value
if(text.length> 15){
alert("too much text")
}
};
<input id="password" type="password" placeholder="password">
you need to mention your code what you tied. Anyway if you don't know try this code
<input type="text" onkeypress="myFunction(this)" maxlength="5">
<script>
function myFunction(e) {
var maxlen= e.maxLength;
if(e.value.length >= maxlen)
alert("Max length is limited to" +maxlen );
}
</script>
Using JQuery:
$("#inputFieldId").on("input propertychange", function(){
var val = this.value;
if(val.length > 15) {
this.value = val.substring(0,15); //comment if you don't want to remove the 16th character
alert("Maximum 15 characters allowed!");
}
});

Say you have a checkbox and beside it you show any numbers, be it 10 and when user clicks on the checkbox then that 10 becomes 9 but if unchecks then it again becomes 10.
<input type="checkbox" id="credits" name="credits" <?php echo $checked;?> /> (10) Credit
The value of credit would be fetched from database.
$(function () {
$('#credits').change(function () {
var currentValue = parseInt($('#credit-amount').text());
var newValue = currentValue + ($(this).prop('checked') ? -1 : 1);
$('#credit-amount').text(newValue);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="checkbox" id="credits" name="credits" /> (<span id="credit-amount">10</span>) Credit

Here is the structure and data of my price
if number is between 0 and 2000 (or in other word the number is less then 2000) - then must appear tax "20"
if number is between 2001 and 5000 - then must appear tax 35
Price:<input type=text name=price><br>
Tax: <input type=text name=tax>
First you should add labels for your inputs, they are linked to the input with ids
<label for="priceInput">Price:</label><input id="priceInput" type=text name=price><br>
<label for="taxInput">Tax:</label><input id="taxInput" type=text name=tax>
And in your jquery:
//Function is executed when the priceInput is changed, so when you enter a value
$("#priceInput").change(function(){
//Test if the value of the input is < 2000 and >0
if (($( "#priceInput" ).val()<2000) && ($("#priceInput").val()>0)) {
//Set the value of the tax input to 20
$("#taxInput").val(20)
}
//test if tyhe value is >2000 and <5000
else if(($( "#priceInput" ).val()<5000) && ($("#priceInput").val()>2000)){
$("#taxInput").val(35)
}
else{
$("#taxInput").val("")
}
});
JSFiddle link
function setPrice()
{
if ($('[name=price]').val() < 2000)
{
$('[name=tax]').val(20);
}
else
{
$('[name=tax]').val(35);
}
}
