在 UIWebView 中创建动态复选框

Question

我正在尝试在 UIWebView 中创建动态复选框。我正在使用此代码：

    NSMutableArray *array = [[NSMutableArray alloc]initWithObjects:@"Sudhaadagdudgdada",@"qwertyuiopo",@"asdfghjkl", nil];

    for (int j = 0; j < array.count; j++)
    {
        NSString *html = [NSString stringWithFormat:@"<div id='check'></div><script> str='';   str += '<input type=\"checkbox\" name=\"one_'+i+'\"  value=\"'+%@+'\" onclick=alert(this.value); />'  document.getElementById(\"check\").innerHTML=str;</script>",[array objectAtIndex:j]];

        [self.webview loadHTMLString:[NSString stringWithFormat:@"%@",html] baseURL:nil];

    }

但是UIWebView中没有checkbox。请帮帮我。

如果您想在 webview 中加载 html，您需要为 it.Update 添加标签，您的代码如下

NSString *html = [NSString stringWithFormat:@"<html><head><div id='check'></div><script> str='';   str += '<input type=\"checkbox\" name=\"one_'+i+'\"  value=\"'+%@+'\" onclick=alert(this.value); />'  document.getElementById(\"check\").innerHTML=str;</script></head></html>",[array objectAtIndex:j]];

//或者如果你想加载你在代码中提到的javascript文件..修改如下

NSMutableArray *array = [[NSMutableArray alloc]initWithObjects:@"Sudhaadagdudgdada",@"qwertyuiopo",@"asdfghjkl", nil];

    for (int j = 0; j < array.count; j++)
    {
        NSString *html = [NSString stringWithFormat:@"<div id='check'></div><script> str='';   str += '<input type=\"checkbox\" name=\"one_'+i+'\"  value=\"'+%@+'\" onclick=alert(this.value); />'  document.getElementById(\"check\").innerHTML=str;</script>",[array objectAtIndex:j]];

        [webView stringByEvaluatingJavaScriptFromString:
        [NSString stringWithFormat:@"%@",html]];

    }

希望对你有所帮助...

我已经解决了：

   NSMutableArray *array = [[NSMutableArray alloc]initWithObjects:@"'Sudhaadagdudgdada'",@"'qwertyuiopo'",@"'asdfghjkl'", nil];
        NSString *html = [NSString stringWithFormat:@"<div id='check'></div><script> var j; var jsArray = new Array %@; str=''; for(j = 0; j< 3;  j++){ str += '<input type=\"checkbox\" name=\"one_'+j+'\"  value = \"'+jsArray[j]+'\" onclick=\"alert(this.value);\" />'+jsArray[j]+'<br/><br/>'; } document.getElementById(\"check\").innerHTML=str;</script>",array];
    NSLog(@"html..%@",html);

        [self.webview loadHTMLString:html baseURL:nil];
