从javascript中具有相同类的文本字段中检索值

Question

Firstly I wanna check the given value in textfield is Number or not.

But I have number of textfields ,the number is depending upon dynamic value from php&yii like as follows

<?php foreach($model->getData() as $donation){  ?>
     Donation For <?php echo  $donation['DonationName'];?>
     <label><b>$</b> <input class="textfld3" style="width:75%" title="First Name" placeholder="Amount" type="text">
    </label>
<?php } ?>

so I wanna get the value of the textfield or textfields in js..

I had also used the jsfunction as

var texts= $(".textfld3").map(function() {
   return $(this).val();
}).get();
alert(texts);

but all the values are showing in alert box along with commas

how should i get the value of textfiled or textfields to check whether it is number or not in js.

Answer 1

Loop through all the textfield using $(".textfld3").each(function() { and find value of textfield one after another. If a textfield having a non numeric value then show alert message and will focus on that textfield.

$(".textfld3").each(function() {
   var currentVal = $(this).val();
   if(isNaN(currentVal)){
        alert("Please enter numeric value");
        $(this).focus();
        return false;
   }
});
