以下是我的代码。我想计算复选框的值。我想要的功能就像,当我选择' #selectall'复选框,它选择所有复选框并计算其值。但是在这段代码中,它正在计算未选中' #selectall'复选框。我该如何解决这个问题?
I fixed the issue. Please see my solution below:
1. First declare a global varibale called "activeFileld"
@property(nonatomic,strong)id activeFiled;
2. Create a method called "registerForKeyboardNotifications"
- (void)registerForKeyboardNotifications
{
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(keyboardWillShow:)
name:UIKeyboardWillShowNotification object:nil]; //Posted immediately prior to the display of the keyboard
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(keyboardWillHide:)
name:UIKeyboardWillHideNotification object:nil]; //Posted immediately prior to the dismissal of the keyboard.
}
3. Called the above method in viewWillAppear:
-(void)viewWillAppear:(BOOL)animated{
[super viewWillAppear:animated];
//Register kryboard Notification
[self registerForKeyboardNotifications];
}
4. Call the Delegate method for UitextFieldd Or UitextView
- (void)textFieldDidBeginEditing:(UITextField *)sender {
self.activeField = sender;
}
- (void)textFieldDidEndEditing:(UITextField *)sender{
self.activeField = nil;
}
- (void)textViewDidBeginEditing:(UITextView *)textView
{
// save the text view that is being edited
_notes = textView.text;
}
- (void)textViewDidEndEditing:(UITextView *)textView
{
// release the selected text view as we don't need it anymore
_activeField = nil;
}
5.
- (void)keyboardWillShow:(NSNotification *)notification
{
if([_activeField isKindOfClass:[UITextField class]]) {
NSDictionary* info = [notification userInfo];
NSLog(@"Dictionary %@",info);
CGRect kbRect = [[info objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue];
kbRect = [self.view convertRect:kbRect fromView:nil];
UIEdgeInsets contentInsets = UIEdgeInsetsMake(0.0, 0.0, kbRect.size.height, 0.0);
self.tableView.contentInset = contentInsets;
self.tableView.scrollIndicatorInsets = contentInsets;
CGRect aRect = self.view.frame;
aRect.size.height -= kbRect.size.height;
UITextField *textField = (UITextField*)_activeField;
if (!CGRectContainsPoint(aRect, textField.frame.origin) ) {
[self.tableView scrollRectToVisible:textField.frame animated:YES];
}
}else if([_activeField isKindOfClass:[UITextView class]]) {
NSDictionary* info = [notification userInfo];
NSLog(@"Dictionary %@",info);
CGRect kbRect = [[info objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue];
kbRect = [self.view convertRect:kbRect fromView:nil];
UIEdgeInsets contentInsets = UIEdgeInsetsMake(0.0, 0.0, kbRect.size.height, 0.0);
self.tableView.contentInset = contentInsets;
self.tableView.scrollIndicatorInsets = contentInsets;
CGRect aRect = self.view.frame;
aRect.size.height += kbRect.size.height;
UITextView *activeTextView = (UITextView*)_activeField;
if (!CGRectContainsPoint(aRect, textField.superview.superview.frame.origin) ) {
[self.tableView scrollRectToVisible:activeTextView.superview.superview.frame animated:YES];
}
}
}
// Called when the UIKeyboardWillHideNotification is received
- (void)keyboardWillHide:(NSNotification *)aNotification
{
UIEdgeInsets contentInsets = UIEdgeInsetsZero;
self.tableView.contentInset = contentInsets;
self.tableView.scrollIndicatorInsets = contentInsets;
}

我删除了这个:
$(document).ready(function(){
$('.pop').popover({content: "Other Expenses 200 <br> Other Expenses 200 <br>Other Expenses 200 <br> ", html: true, placement: "right", trigger: "focus"});
});

一切似乎都有效......你的问题在哪里...你的代码正在检查&amp;取消选中...!

Finally I found the problem it was because of I closed the $(document).ready(function() before the execution
$(document).ready(function () {
// Select all
$('#selecctall').click(function (event) { //on click
if (this.checked) { // check select status
$('.checkbox1').each(function () { //loop through each checkbox
this.checked = true; //select all checkboxes with class "checkbox1"
});
} else {
$('.checkbox1').each(function () { //loop through each checkbox
this.checked = false; //deselect all checkboxes with class "checkbox1"
});
}
});
**** // actually i closed the function here this should be at the end
//Addition for checked value
$('input').click(function () {
var sum = 0;
$('input[type=checkbox]:checked').each(function () {
sum += Number($(this).val());
});
console.log(sum);
$("#sum").html(sum);
});
});
