get_attribute_by_number

get_attribute_by_number($number,$name_attr,$frame=-1); - this function is used to get the attribute value of an element on the page, finding it by the specified number.

the input Function accepts parameters:

  • $number – the number by which we find the element we need on the page (int) . Element numbers start with 0 and different types of elements have their own numbering.To find out the item number, you can use either the item inspector or the context menu, or view it in the list of items.
  • $name_attr – name of the attribute to get (string). The entire set of attributes that an element has can be found in the element inspector.
  • $frame – the number of the frame in which we are looking for the element (string). Frame numbers start from zero. By default, -1 - the element is not in the frame. You can find out the number of the frame that contains the item you need from the task inspector, the context menu, and the item list panel.
    With version 4.6.41 of postpone: you can pass nested frames, the principle is the same, a string is numbered frames separated by : for example, if you transfer "1:0:5" - will the selected frame number 1 in it under the frame with the number 0 and the subframe number 5
    Since version 7.0.38, you can pass "url=>XXX", then search for the frame that contains the specified src, or pass "name=>XXX" - then the frame will be searched by the specified part of the name.

    After the function returns the result of their work in the script :
  • attribute value – the value of the specified attribute from the found element return type string
  • false to find this element failed (e.g. no items that meet the specified criteria or not this frame), the return type boolean,

    PHP example:

    <?php $xhe_host = "127.0.0.1:7013";
     
    //connect the object to control the emulator, if not already connected
    if(!isset($path))
      $path = "../../../Templates/xweb_human_emulator.php";
    require($path);
     
    //Start
    echo "<hr> <font color = blue> anchor->".basename(__FILE__)."</font> <hr>";

    echo "5.Get the href attribute of the link with the 7th number in the zero frame:";
    echo $anchor->get_attribute_by_number(7, "href", 0)."<br>";
