    hello,

     

    i tried to build a very simple function, and i failed allready. dissapointing. I can not find where i went wrong. plz help me.

     

    button 1: it should change the wordt "haai" to "yoyo" and then to "hallo". it does change haai to yoyo, but not beyond.

    button 2: it should change color (it does, so works fine).

     

    regards, ronald

     

    <script>
    function hello() {
    var x = document.getElementById("hey");
    if(x = "haai"){
    var y = "yoyo";
    }else{
    var y = "hallo";
    }
    document.getElementById("hey").innerHTML = y;
    }
    function red(){
    document.getElementById("hey").style.color = "red";
    }
    </script>
    <button onClick="hello()">click me</button>
    <button onClick="red()">click me</button>
    <p id="hey">haai</p>

    reference guide prob

    in General

    Posted

    hi there,

     

    i got a prob with finding refence for attributes. perhaps im not looking right, or missing things.

     

    i started looking for div attributes, finding on w3s this:

    - The <div> tag also supports the Global Attributes in HTML.

    - The <div> tag also supports the Event Attributes in HTML.

     

    i also checkt this site:

    http://www.w3.org/TR/html401/struct/global.html#edef-DIV

    at 7.5.4 there is it about the div

     

    now, i got this: (and it works just fine)

     

    <!doctype html>
    <html>
    <head>
    <title>my first website</title>
    <style type="text/css">
    #myfirstdiv {border:2px solid red;
    width:100px;
    position:absolute;
    top:200px;
    left:100px;}
    </style>
    </head>
    <body>
    <div id="myfirstdiv">hello there!</div>
    </body>
    </html>
    i figure, this are examples of attributes: top, left, position, border, width (thats what i think at least..)
    but i dont see those above on the reference links.
    do i interpret something wrong?
    regards, R
