XPath using JScript

I'm a beginner with Selenium and I'm curious about how the value in the text box is loaded when there's no value visible in the HTML tag:

<input type="text" name="qty" id="qty" maxlength="5" value="" title="Qty" class="quantity-input qty"

Could it be coming from JavaScript?

<script type="text/javascript">
    jQuery(document).on('click','.quantity-plus',function(){
        var qty = jQuery.trim(jQuery('#qty').val());
        if(qty < 99999)
        {   
        var moq = jQuery('input[name=opinions]:checked').attr('data-moq');
        var incrementquantity = jQuery('input[name=opinions]:checked').attr('data-incrementquantity');
        var incrementmode = jQuery('input[name=opinions]:checked').attr('data-incrementmode');
        var qty = jQuery.trim(jQuery('#qty').val());
        jQuery('.moqerror').html('');
        if(Number(qty) >= Number(moq) && parseInt((qty-moq)%incrementquantity) == 0)
        {
            var newqty = parseFloat( parseFloat(qty) + parseFloat(incrementquantity));
            jQuery('#qty').val(newqty);
            updateEstimatePrice();
        }

Answer №1

According to the code, the value attribute is being set using the val() function.

var newqty = parseFloat( parseFloat(qty) + parseFloat(incrementquantity));
jQuery('#qty').val(newqty);

I'm a bit puzzled by the mention of 'XPath' in the title of the question, which leads me to believe I may be misunderstanding something.

UPDATE: Regarding the Selenium query:

It appears to be quite broad, but here's how I would approach it:

Prerequisites:

  1. Jasmine testing framework
  2. promises
  3. webdriverjs's control flow using promises
  4. How angular protractor uses promises

If you're comfortable with those requirements:

First, set up Selenium with protractor (which can be complex), and then you could potentially try this approach (untested):

describe("Checking selectall, ", function() {
  it("exists,", function() {
    var qty = element(By.css('input#qty'));
    expect(browser.isElementPresent(qty)).toEqual(true);
    it("clicks loads with a value", function() {
      qty.getAttribute("value").then(function(data) {
          return console.log("qty.value", data);
        });
      });
    });
  });
});
