js语句
document.documentElement.getElementsByClassName('这里写你要消除的空间的class里面的字符串')[0].style.display = 'none'
具体用法：
- (void)webViewDidFinishLoad:(UIWebView *)webView{
[webView stringByEvaluatingJavaScriptFromString:@"document.documentElement.getElementsByClassName('adpic')[0].style.display = 'none'"];
}
2. 获得UIWebView的标题
- (void)webViewDidFinishLoad:(UIWebView *)webView{
NSString *theTitle=[webView stringByEvaluatingJavaScriptFromString:@"document.title"];
}
3. 获取页面的URL
- (void)webViewDidFinishLoad:(UIWebView *)webView{
NSString *currentURL = [webView stringByEvaluatingJavaScriptFromString:@"document.location.href"];
}
4. 修改页面元素的值
- (void)webViewDidFinishLoad:(UIWebView *)webView{
NSString *js_result = [webView stringByEvaluatingJavaScriptFromString:@"document.getElementsByName('q')[0].value='朱祁林';"];
}
5. 表单提交
- (void)webViewDidFinishLoad:(UIWebView *)webView{
NSString *js_result2 = [webView stringByEvaluatingJavaScriptFromString:@"document.forms[0].submit(); "] }
