从javascript中具有相同类的文本字段中检索值

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.

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;
   }
});

From a quick view into your code, it looks to me, texts is an array, so you could run through this array

var texts= $(".textfld3").map(function() {
       return $(this).val();
    }).get();
for ( var i = 0; i < texts.length; i++ ) {
 alert(texts[i]);
}

You have to pass key and value parameter in map function so you can return value of all text fields by value, here ele variable is value which is reference one element of that class selector

$("#btn").click(function(){
var texts= $(".textfld3").map(function(key,ele) {
       return $(ele).val();
       //return ele.value
    }).get();
    console.log(texts);
})
