在UIWebView的内容加载完之后,可以利用javascript获取其页面内的数据,核心就是通过UIWebView的方法:
NSString *string = [awebView stringByEvaluatingJavaScriptFromString:@"document.getElementById('field_2').value;" ];
以下是一些常用的js脚本:
thisURL = document.URL;
thisHREF = document.location.href;
thisSLoc = self.location.href;
thisDLoc = document.location;
thisTLoc = top.location.href;
thisPLoc = parent.document.location;
thisTHost = top.location.hostname;
thisHost = location.hostname;
thisTitle = document.title;
thisProtocol = document.location.protocol;
thisPort = document.location.port;
thisHash = document.location.hash;
thisSearch = document.location.search;
thisPathname = document.location.pathname;
thisHtml = document.documentElement.innerHTML;
thisBodyText = document.documentElement.innerText;//获取网页内容文字
thisBodyText = document.body.innerText;//获取网页内容文字
也可以通过同样的方法去设置页面内容(比如帮用户输入表单数据)
比如:
NSString *string = [awebView stringByEvaluatingJavaScriptFromString:@"document.getElementById('field_2').value='a value';" ];
就可以修改field_2的值了
同样也可以去模拟页面内按钮的点击,提交页面,比如:
document.getElementById('aButtonName').click();
或者,假设知道按钮是第几个input标签(假设为第一个)
document.getElementsByTagName('input').item(0).click();
也可以设置checkBox的状态:
document.getElementById('aCheckBoxId').checked=true;
