如何將目標C中的數組顯示爲HTML或JavaScript，以顯示內容陣列上的HTML一個buttonclick，如何將目標C中的數組顯示到HTML或JavaScript中，以在HTML中按鈕單擊顯示數組的內容
下面的代碼是我的.m文件代碼的
[webView loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle]pathForResource:@"Array"ofType:@"html"]isDirectory:NO]]];
NSString *path = [[NSBundle mainBundle] pathForResource:@"Example" ofType:@"csv"];
NSString *contents = [NSString stringWithContentsOfFile:path encoding:NSASCIIStringEncoding error:nil];
NSArray *lines = [contents componentsSeparatedByCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"\n,"]];
for (NSString* line in lines) {
NSLog(@"%@", line);
}
NSLog(@" %d", [lines count]);
[self.webView performSelectorOnMainThread:@selector(stringByEvaluatingJavaScriptFromString:) withObject:[NSString stringWithFormat:@"checkContents = new Array%@",lines] waitUntilDone:NO];
以下是我的HTML文件中的代碼，
function checkContents(Lines) {
// alert("test...");
alert(checkContents[0]);
// alert(document.lines[0]);
if (typeof(checkContents)=='undefined')
....
else {
if (checkContents.length == 0)
....
else {
for (i=0; i<checkContents.length; i++) {
}
}
}
}
<body onload="checkContents()">
<div class="greybutton" onClick="javascript:checkContents()">contents</a></div>
</body>
當我運行這個編程的，它顯示未定義的警報輸出，我是否缺少HTML文件中的任何代碼或我犯的錯誤。
