I have a input box like this

<input type="text" class="form-control" onblur="getProductqty('+this.value+')"
    placeholder="0" id="'+productSizeId+'">

And i am trying to get the value of the input field by the getProductqty() function.

I have tried like this

    function getProductqty(productQnty)
    {
        console.log(productQnty);
        var $this = jQuery(this);
        console.log($this.value );
    }

From the both i found the undefined value. Please any help. Thank you in advance.

• 2 You're passing a hardcoded string as the argument. I have difficulty believing that it is ing out as undefined. (Possibly you are generating that HTML with embedded JS using PHP or something. You need to provide a real minimal reproducible example) – Quentin Commented Aug 9, 2018 at 5:58

You can simply pass the reference this to getProductqty function and get the value of input like

function getProductqty(input){
  console.log(input.value)
}

<input type="text" class="form-control" onblur = "getProductqty(this)" placeholder="0" id="productSizeId">

You can simply pass this and get it in the function and access the value property on it. Or if you want to pass this.value then you dont need all those extra + and '

function getProductqty(value){
  console.log(value);
}

<input type="text" class="form-control" onblur = "getProductqty(this.value)" placeholder="0">
