如何使用UIWebView的时候自动填充数据使用RegsEx找到登录表单?
我用下面的代码来获取所有形式的数据:
int NoOfForms = [[self.browser stringByEvaluatingJavaScriptFromString:@"document.forms.length"] intValue];
NSMutableArray *formData = [[NSMutableArray alloc] initWithCapacity:0];
for (int i = 0 ; i < NoOfForms ; i++)
{
// total number of elements in each form
int elementsInForm = [[self.browser stringByEvaluatingJavaScriptFromString:[NSString stringWithFormat:@"document.forms[%d].elements.length",i]] intValue];
for (int j = 0; j < elementsInForm; j++)
{
// element id of each element
NSString *elementID = [NSString stringWithFormat:@"document.forms[%d].elements[%d].id",i,j];
// element value of each element
NSString *elementValue = [NSString stringWithFormat:@"document.forms[%d].elements[%d].value",i,j];
// dictionary for all values of each element
NSDictionary *elementData = [NSDictionary dictionaryWithObjectsAndKeys:
[NSNumber numberWithInt:i],@"form No",
[NSNumber numberWithInt:j],@"element No",
[self.browser stringByEvaluatingJavaScriptFromString:elementID],@"elementID",
[self.browser stringByEvaluatingJavaScriptFromString:elementValue],@"elementValue",nil];
// add each element data to a mutable array.
[formData addObject:elementData];
}
}
并有下面的代码把数据返回到各自的领域:
for (int i = 0 ; i < [dataArray count]; i++)
{
NSDictionary *elementDict = [dataArray objectAtIndex:i];
int formNumber = [[elementDict objectForKey:@"form No"] intValue];
int elementNumber = [[elementDict objectForKey:@"element No"] intValue];
NSString *formElementID = [elementDict objectForKey:@"elementID"];
NSString *formElementValue = [elementDict objectForKey:@"elementValue"];
if ([[self.browser stringByEvaluatingJavaScriptFromString:[NSString stringWithFormat:@"document.forms[%d].elements[%d].id",formNumber,elementNumber]] isEqualToString:formElementID])
{
[self.browser stringByEvaluatingJavaScriptFromString:[NSString stringWithFormat:@"document.forms[%d].elements[%d].value='%@'",formNumber,elementNumber,formElementValue]];
}
}
现在我只想提交登录form..how找到它?
我遇到更多的一个问题:当我的代码把密码进入该领域,一些网站如mail.google.com不会让这种情况发生,即它倒空密码字段。 如何解决这个问题呢 ?
更新:目前我已经能够登录在mail.google.com但却无法做了belleandclive.com相同。 这是网站实现其登录表单任何的安全措施?
