In Angularjs reference to two-way data binding, you will certainly think of ng-model instructions.
First, Ng-model
The Ng-model directive is used to bind input, select, textarea, or custom form controls to properties in the scope that contains them. It binds the value of an operation expression in the current scope to a given element. If the property does not exist, it is implicitly created and added to the current scope.Always use Ng-model to bind a property in the previous data model of scop

One thing I ' ve learned over the last few years are to-use techniques in I applications Tain, especially if you leave the project and have to come back to it at a later time.
Besides error handling and commenting, I try to automate as much as possible to make maintenance a cake-walk. One area, can be tremendously automated are implementing date structures in your application.
For instance ... if you ' re building a ecommerce application, you'll eventually
The dynamic is just beginning with the following:
function Limittonum () {
if (This.text!= "-" isNaN (This.text)) {
This.text = ';
}
}
a_txt.onchanged = Limittonum;
b_txt.onchanged = Limittonum;
c_txt.onchanged = Limittonum;
... Found a little cumbersome, suddenly remembered ' prototype ':
TextField.prototype.onChanged = function () {
if (This.text!= "-" isNaN (This.text)) {
This.text = ';
}
This limits all dynamic text entry boxes in Flash.

This example describes how JavaScript detects and restricts the number of check boxes. Share to everyone for your reference. Specifically as follows:
Here use JavaScript to determine whether the check box is checked, and you can limit the number of check box, this is a more practical JS form judgment example, check box is selected to let a lot of people wonder, now good, this piece of code to help you solve the problem.
The screenshot of the running
At work, you always encounter a lot of text boxes that prohibit the input of non-numeric characters, such as mobile phone number and zip code.
Copy Code code as follows:

This article describes the JS simple implementation of the Click button in the form of dynamic increase in the number of input box method. Share to everyone for your reference. Specifically as follows:
Here to demonstrate the click of the button to dynamically increase the number of input boxes, the default is no input box, click the button, the input box will continue to increase, every click, add a, feel pretty good, I hope to help you.
The effect
Sometimes you don't need a tree control all nodes display a check box, and then you need to hide the checkbox for the corresponding node, the code reads as follows:
M_treecontrol is the CTreeCtrl variable associated with the tree control, Nrootitem is the root node defined by Htreeitem;
M_treecontrol.setitemstate (nrootitem,indextostateimagemask (0), tvis_stateimagemask);//Hide root node check box
If you need to hide the checkbox of a node in the OnInitDialog () function of a class, you nee

There are two forms of dialogs in MFC, one modal dialog (Model dialog box) and one non-modal dialog (modeless dialog box).
A modal dialog (Model dialog box)
In the process of running the program, if a modal dialog box appears, the main window will not be able to send the message until the modal dialog box exits before it can be sent.
Click the OK button in the modal dialog box and the modal dialog will be destroyed.
To create a modal dialog box code:
Create a modal dialog box
Ctestdialog TD;
Q: The program is based on the dialog box, I display two dialog boxes, one behind the other, here is my practice:
CMyApp::InitInstance (){ ... CMyDialog1 dlg1; m_hMainWnd = dlg1; int result = dlg1.DoModal (); CMyDialog2 dlg2; result = dlg2.DoModal (); ...}
In the above code, first a dialog box is appropriately invoked, but the second dialog box does not, for example, invoke Dlg2. DoModal () returns-1, and when I step through it I find
Text boxes are often used in editing documents, for example, sometimes to prevent text or pictures from moving, we use text boxes to frame text or pictures. The general action method is to first enter the contents of the previous text box, after the content is filled, then move the mouse to the next text box and then continue typing. This is a phenomenon, just when the content input is complete, if you add

Lists and combo boxes are another user-selectable interface component for selecting items in a group, and the combo box can also enter a new selection.ListA list (JList) is represented in the interface as a list box, which is an object of the JList class or its subclasses. The program can include multiple text selection entries in the list box. There are two types of event sources for list events:
One is the mouse double-click an option: The
original standard position of the box relative to it. The relatively positioned box is still in the standard flow, and the box behind it still treats it as a standard flow.◊absolute: Absolute positioning, the position of the box is offset by its containing frame. The absolutely positioned box is detached from the standard flow. It has no effect on the positioning of the adjacent box, and the other boxes are as if the box does not exist.◊fixed: fixed

I admit that some places do not write well... Silly. I wrote multithreading for the first time. Not a lot of things. Just look at it.
With queues and multithreading, you can show multiple prompt boxes at the same time, but the number of prompt boxes displayed at the same time will not exceed the set value, if the value is exceeded, it will be displayed after the box is closed o
