    Javascript: Object doesn't support this property or method

    Hi everybody,

    Problem with dragging effect of resizing is working but having problem with setting a flag to determine if mouse button is click or not. Is there anyone knows how to fixed this? I used several ways to do this as shown below, all telling me the error below. I used IE 6 w/ SP1.
    The error comes from onmousedown"mou sedown()".


    Error message:

    Microsoft JScript runtime error: Object doesn't support this property or method


    Approaches made:

    [HTML]var mousedown = false;[/HTML]

    inside mousedown,

    [HTML]mousedown = true;[/HTML]

    inside mousemove,

    [HTML]if (mousedown)

    {

    ....

    }[/HTML]


    Partial Codes:

    [HTML]
    <head>
    <title>Untitl ed Page</title>
    <script type="text/javascript" language="javas cript">
    var lLeft = 0;
    var lTop = 0;

    var mousedown;

    function mouseDragImage( obj)
    {
    ....
    var dLeft, dTop;
    var ev = window.event;

    // if (window.event.b utton == 1)
    // if (ev.button == 1)
    // if (mousedown)
    // if (mousedown == 'true')
    if (mousedown == 1)
    {
    if(ev.pageX || ev.pageY){
    newx = ev.pageX;
    newy = ev.pageY;
    }
    else
    {
    newx = ev.clientX;
    newy = ev.clientY;
    }

    .....
    }
    }

    function mousedown()
    {

    // mousedown = 'true';
    // mousedown = true;
    if (mousedown != null || mousedown > 0)
    {
    mousedown = 1;
    }
    }

    function mouseup()
    {
    // mousedown = 'false';
    // mousedown = false;
    mousedown = 0;
    }


    .....
    </script>
    </head>

    <body>
    <input id="Text1" type="text" /><br />
    <img id="Img3" name="Img3" src="images/rock.jpg" onmouseover="mo useOver(this)" onmousedown="mo usedown()" onmousemove="mo useDragImage(th is)" onmouseout="mou seup()"/><br /><br />
    <input id="Button1" type="button" value="button" />

    </body>
    [/HTML]

      you might try a on mouse down and on mouse up such as
      onmousedown="mo usepress(0);" onmouseup="mous epress(1);"
      var mousestate
      function mousepress(stat e) {
      mousestate = state;
      }

          Hi, I'm having this problem with getElementBy*** *****
          I have an xmlhttprequest call which works as far as
          Code:
          something = http.responseText.split("||");
          the request is calling a php script which queries a database giving me two variables $numfields and $numrows, and two arrays, array1[] and array2[][], self-explantory. When I try to assign the two variables using getElementByNam e, or when I try to assign either array using getElementById I get the same error "Object doesn't support this property or method"
          Code:
          numrows = result.getElementByName("numrows").innerHTML;
numfields = result.getElementByName("numfields").innerHTML;
array1 = something.getElementById("array1").innerHTML;
          All my text fields have ID's. Does anyone have any insight into this?

              Post your HTML code (your text fields).

                  when using getbyName your text field must have name
                  and when using getbyId ur text filed must have an id

                  Sometimes only one of them working somtime both depends on the browser mode

                      just use single quotes instead of double quotes,

                      Wrong
                      something.getEl ementById("arra y1").innerHTM L;
                      Right
                      something.getEl ementById('arra y1').innerHTML;
