Java GWT中的JSNI方法
在我遇到这种情况之前,它是有效的: JS侧:Java GWT中的JSNI方法,java,javascript,gwt,jsni,Java,Javascript,Gwt,Jsni,在我遇到这种情况之前,它是有效的: JS侧: jsMethod : function(){...} public static native void javaMethod(JavaScriptObject obj) /*-{ var test = null; test = ... ; test.jsMethod(); }-*/; GWT Java端: jsMethod : function(){...} public static native void
jsMethod : function(){...}
public static native void javaMethod(JavaScriptObject obj) /*-{
var test = null;
test = ... ;
test.jsMethod();
}-*/;
GWT Java端:
jsMethod : function(){...}
public static native void javaMethod(JavaScriptObject obj) /*-{
var test = null;
test = ... ;
test.jsMethod();
}-*/;
问题是当我尝试这样做的时候
JS侧
jsMethod : function(a, b){... return string}
String a = 'yes'
String b = 'no'
public static native void javaMethod(JavaScriptObject obj) /*-{
var test = null;
test = ... ;
var testString = null;
testString = test.jsMethod(a, b);
}-*/;
GWT Java端
jsMethod : function(a, b){... return string}
String a = 'yes'
String b = 'no'
public static native void javaMethod(JavaScriptObject obj) /*-{
var test = null;
test = ... ;
var testString = null;
testString = test.jsMethod(a, b);
}-*/;
我将把参数从GWT传递到JS,然后返回一个字符串,但我不知道如何实现它。谢谢。就像Java一样。返回一个字符串
public static native String javaMethod(JavaScriptObject obj) /*-{
var test = null;
test = ... ;
var testString = null;
testString = test.jsMethod(a, b);
return testString;
}-*/;
您可以向本机JavaMethod添加参数
public static native String javaMethod(JavaScriptObject obj, String a, String b) /*-{
var test = null;
test = ... ;
var testString = null;
testString = test.jsMethod(a, b);
return testString;
}-*/;
好的,但我不知道如何传递参数,是否需要:“[instance expr.]@class name::method name(param signature)(arguments)”?
