Here is caller button samples in html:
<input type='button' value='Call' onclick='Test()'>
And here are some functions I tried and which were not worked:
<script type="text/javascript">
function Test() {
com.tests.client.Test_GoogleWeb_JSNI::Callee()();
}
</script>
But we are not able to call Callee().How we can achieve this?I mean how we can invoke JSNI function from javascript?
Help would be appreciated.
It's very easy. You need to "export" your function written in GWT (or it can be another JSNI) function.
Here is the relevant documentation: http://code.google.com/webtoolkit/doc/latest/DevGuideCodingBasicsJSNI.html#calling
So in your case:
In your GWT code:
public static void Caller() /*-{
...
}-*/
public static native void exportStaticMethod() /*-{
$wnd.Callee =
$entry(@com.tests.client.Test_GoogleWeb_JSNI::Callee());
}-*/;
Then you call exportStaticMethod()
somewhere, even in your onModuleLoad. << YOU MUST DO THIS
Then you can call Callee()
from your handwritten javascript code.
Your code for the button:
<input type='button' value='Call' onclick='$wnd.Callee();'>
