我创建了一个示例演示应用程序,其中包含以下html页面。
<!doctype html>
<!-- The DOCTYPE declaration above will set the -->
<!-- browser's rendering engine into -->
<!-- "Standards Mode". Replacing this declaration -->
<!-- with a "Quirks Mode" doctype is not supported. -->
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
<script>
function alert1(p1) {
alert("P1 is "+p1);
}
</script>
<!-- -->
<!-- Consider inlining CSS to reduce the number of requested files -->
<!-- -->
<link type="text/css" rel="stylesheet" href="Sample_JS.css">
<!-- -->
<!-- Any title is fine -->
<!-- -->
<title>Web Application Starter Project</title>
<!-- -->
<!-- This script loads your compiled module. -->
<!-- If you add any GWT meta tags, they must -->
<!-- be added before this line. -->
<!-- -->
<script type="text/javascript" language="javascript" src="sample_js/sample_js.nocache.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
<script type="text/javascript">
var app = angular.module('MyApp', [])
app.controller('MyController', function ($scope, $window) {
$scope.nameList = [];
$scope.ShowAlert = function () {
$scope.nameList.push($scope.nameFieldContainer);
$window.alert("Hello Angular : "+$scope.nameFieldContainer);
}
});
</script>
</head>
<!-- -->
<!-- The body can have arbitrary html, or -->
<!-- you can leave the body empty if you want -->
<!-- to create a completely dynamic UI. -->

<body>
<!-- OPTIONAL: include this if you want history support -->

我的gwt控制器类如下
package com.google.client;
import com.google.shared.FieldVerifier;
import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.core.client.GWT;
import com.google.gwt.event.dom.client.ClickEvent;
import com.google.gwt.event.dom.client.ClickHandler;
import com.google.gwt.event.dom.client.KeyCodes;
import com.google.gwt.event.dom.client.KeyUpEvent;
import com.google.gwt.event.dom.client.KeyUpHandler;
import com.google.gwt.user.client.rpc.AsyncCallback;
import com.google.gwt.user.client.ui.Button;
import com.google.gwt.user.client.ui.DialogBox;
import com.google.gwt.user.client.ui.HTML;
import com.google.gwt.user.client.ui.Label;
import com.google.gwt.user.client.ui.RootPanel;
import com.google.gwt.user.client.ui.TextBox;
import com.google.gwt.user.client.ui.VerticalPanel;
/**
* Entry point classes define <code>onModuleLoad()</code>.
*/
public class Sample_JS implements EntryPoint {
/**
* The message displayed to the user when the server cannot be reached or
* returns an error.
*/
private static final String SERVER_ERROR = "An error occurred while "
+ "attempting to contact the server. Please check your network "
+ "connection and try again.";
/**
* Create a remote service proxy to talk to the server-side Greeting service.
*/
private final GreetingServiceAsync greetingService = GWT
.create(GreetingService.class);
/**
* This is the entry point method.
*/
public void onModuleLoad() {
final Button sendButton = new Button("Add");
final TextBox nameField = new TextBox();
nameField.setText("GWT User");
final Label errorLabel = new Label();
// We can add style names to widgets
sendButton.addStyleName("sendButton");
// Add the nameField and sendButton to the RootPanel
// Use RootPanel.get() to get the entire body element
RootPanel.get("nameFieldContainer").add(nameField);
RootPanel.get("sendButtonContainer").add(sendButton);
RootPanel.get("errorLabelContainer").add(errorLabel);
// Focus the cursor on the name field when the app loads
nameField.setFocus(true);
nameField.selectAll();
// Add a handler to close the DialogBox
closeButton.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event) {
dialogBox.hide();
sendButton.setEnabled(true);
sendButton.setFocus(true);
}
});
// Create a handler for the sendButton and nameField
class MyHandler implements ClickHandler, KeyUpHandler {
/**
* Fired when the user clicks on the sendButton.
*/
public void onClick(ClickEvent event) {
//sendNameToServer();
MyTestJS.hasPopupBlocker(nameField.getValue());
}
/**
* Fired when the user types in the nameField.
*/
public void onKeyUp(KeyUpEvent event) {
if (event.getNativeKeyCode() == KeyCodes.KEY_ENTER) {
sendNameToServer();
}
}
// Add a handler to send the name to the server
MyHandler handler = new MyHandler();
sendButton.addClickHandler(handler);
nameField.addKeyUpHandler(handler);
}
}
我试图通过使用gwt按钮组件从本地js方法调用anularjs函数,但我不能。
package com.google.client;
public class MyTestJS {
public static native boolean hasPopupBlocker(String name)/*-{
if (!name){
name = "Please enter name";
}else{
name = "Hello "+ name ;
}
return $wnd.ShowAlert();
}-*/;
}
如何从gwt调用angularJs ShowAlert()函数(通过点击java代码中的按钮或以其他方式)? 请建议。 任何帮助都会很明显...... 提前谢谢。
