我正在使用Xcode开发一个WebKit Safari插件。如何从-webPlugInStart
调用JavaScript?
答案 0 :(得分:1)
首先你应该记住包含视图:
+ (NSView *)plugInViewWithArguments:(NSDictionary *)arguments {
return [[self alloc] initWithArguments:arguments];
}
- (id)initWithArguments:(NSDictionary*)arguments {
if((self = [super init])) {
webView = [[[arguments objectForKey:WebPlugInContainerKey] webFrame] webView];
}
return self;
}
如果有,请参阅"Using JavaScript From Objective-C"上的文档。 E.g:
- (void)webPlugInStart {
WebScriptObject *scriptObj = [webView windowScriptObject];
NSArray *args = [NSArray arrayWithObjects:
@"someString", [NSNumber numberWithInt:42], nil];
[scriptObj callWebScriptMethod:@"myJsFunction" withArguments:args];
}

这真的就像打电话一样简单。
WebScriptObject *jsObj = [webView windowScriptObject];
NSString *script = @"$('That's a HUGE vageen.').text('#yourDiv');";
[scriptObject evaluateWebScript:script];
Ta da!并且不要让人们做这种奇怪的缺乏 - 阻止你像 sexiness 那样......
DOMDocument *myDOMDocument = [[webView mainFrame] DOMDocument];
DOMElement *paraBlock = [myDOMDocument getElementById:@"thatDiv"];
DOMElement *newPara = [myDOMDocument createElement:@"p"];
DOMText *newText = [myDOMDocument createTextNode:@"John Resig is a fool."];
[newPara appendChild:newText];
[paraBlock appendChild:newPara];
就像jQuery! 但它是Objective-C。哦,欢乐!
