Hi i need some guidance or pointer of how to do a wrapper of a javascript library.

I make a simple javascript “myTest.js” with a function:

function myFunction(num)
{
    if(num==1){
        return "Hello World1!";
    }else{
        return "bye World2!";
    }
}

And the i called in my simple HTML:

<html>
  <head>
    <script type="text/javascript" SRC="myLib.js">  

</script>
    <title>Tutorial: HelloWorld</title>
  </head>
  <body>
    <h1>Example HTML</h1>
    <input type="button" value="button" onclick="alert(myFunction(1))">
  </body>
</html>

Obviously this example is very easy to do in GWT.

This is only to i learn how do i do a gwt-wrapper of the javascript file to be able to call the function in GWT.

Thanks

ok, i need a more powerfull example if i have an js file with this function:

  function MyObject() {
    // properties in config
    this.displayname = 'First Last';
    this.username = '1060';
    this.domain = '12.18.34.234';
    this.authname =  '1060';
    this.password = '1060';
    this.transport = 'w34s';
   }

and in html is script part i made this call

var myObj = new MyObject();

how do i make this in GWT??

do i have to create the class MyObject?
with the fields presented in javascript?

    If you want to call native javascript in GWT you can define a native method in your GWT class like this:

    private native void test(String argument)/*-{
    myFunction(argument);
}-*/

    When you call the method test(“foo”) from GWT it will call the native js function myFunction(“foo”);
