Question

I am trying to call my Javascript method from my java in GWT
below is what i am doing

public void onModuleLoad() {
    jsniAlert("test");
}

private static final native void jsniAlert(String test) /*-{
    $wnd.alert(test);
    $wnd.testJavascript();
}-*/;

HelloJSNI.html (the main html class which use to open my application in war folder)

<script type="text/javascript" language="javascript"  
    src="hellojsni/hellojsni.nocache.js"></script>

<script type="text/javascript">
    function testJavascript(var input) {
        window.jsniAlert();
        var var1inJS = "Default value";

        alert("Value of Var1 = " + var1inJS);
        var1inJS = input;
        alert("Value of Var1 = " + var1inJS);

        var var2inJS = "Waht is the value of Var2";

        alert("Value of Var2 = " + var2inJS);   
    }

but when i run my application there’s an exception

javascriptexception:object doesn't support property or method 'testjavascript'

Answer 1

You have an error in your testJavascript function, so it is not getting loaded, and you can’t call it.

Change this:

function testJavascript(var input) {

to this

function testJavascript(input) {  //notice that var keyword is not used to define parameters
