我的项目中包含HTML文件。我用它来初始化显示自定义Google地图的WebView
。我是OSX应用程序的新手(我来自iOS),所以这对我来说都是新的...
我希望HTML文件的某些部分是“动态的”,尤其是在javascript函数中。
以下是我获取本地文件的URL并加载WebView的方法:
-(void)awakeFromNib
{
NSString *indexPath = [[NSBundle mainBundle] pathForResource:@"index" ofType:@"html"];
[[mapView mainFrame] loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:indexPath]]];
[[[mapView mainFrame] frameView] setAllowsScrolling:NO];
[mapView setNeedsDisplay:YES];
}
这是HTML文件:

<div id="map_area" style="position: absolute; top: 0; right: 0; bottom: 0; left: 0"> </div>
<script type="text/javascript">
//map = new GMap2(document.getElementById("map_area"));
//map.setCenter(new GLatLng(37.4419, -122.1419), 13);
var myLatLng = new google.maps.LatLng(0, -180);
var mapOptions = {
zoom: 1,
center: myLatLng,
mapTypeId: google.maps.MapTypeId.TERRAIN
};
var map = new google.maps.Map(document.getElementById('map_area'), mapOptions);
var flightPlanCoordinates = [
new google.maps.LatLng(37.772323, -122.214897),
new google.maps.LatLng(21.291982, -157.821856),
new google.maps.LatLng(-18.142599, 178.431),
new google.maps.LatLng(-27.46758, 153.027892)
];
var flightPath = new google.maps.Polyline({
path: flightPlanCoordinates,
strokeColor: '#FF0000',
strokeOpacity: 1.0,
strokeWeight: 2
});
flightPath.setMap(map);
</script>
</body>
</html>
如何动态更改javascript?我希望能够添加/删除坐标并绘制多条折线。在iOS中搞乱HTML / XML时,我使用了一些名为HPPLE的东西,它通过HTML / XML文件解析...
任何有关如何处理此问题的帮助都将受到赞赏......或者如果您知道更好的方式来调用javascript函数,请随时告诉我。

从文件中读取
NSString * selfilecontent = [NSString stringWithContentsOfFile:path];
[texteditor setString:selfilecontent]; //shown in textView
写入文件
[[[texteditor textStorage]string] writeToFile:@"/Volumes/test1.rtf" atomically:YES encoding:NSUnicodeStringEncoding error:nil];
执行webScript:
NSString *href = [[aWebView windowScriptObject] evaluateWebScript:@"location.href"];
