Binding events for future element bindings cannot be used with BIND,
1, you can use live instead, but to pay attention to the version of jquery, according to the official documents, from the beginning of 1.7 do not recommend live and delegate, 1.9 to remove live.
2, recommended on instead (note: 1.7 and above version to support). Usage: On (EVENTS,[SELECTOR],[DATA],FN)
Copy Code code as follows:
is available in $ (function () {})
$ (document). On ("click", "#testDiv", function () {
$ (this) here means $ ("#testDiv"), not $ (document)
});
3. When you only want to bind a one-time event handler to a specific event (like click) for each matching element, using. One () instead of on, note that it is not possible to execute once on all [selector], but to do so on all of these [select], The elements of the future are also effective.
4, if a DIV has an increase in the deletion of three buttons need to bind events, like the following write:
Copy Code code as follows:
$ (' #btn-add '). Click (function () {});
$ (' #btn-del '). Click (function () {});
$ (' #btn-edit '). Click (function () {});
The disadvantage of this writing: see the structure of the three links, there is no reason for event bubbling.
Take a look at some of the ideas recommended by Coffeedeveloper for jquery's event bindings, which can be written in this way:
Copy Code code as follows:
$ ("#btnContainer"). Coffee ({
Click: {
' #btn-add ': function () {//do something},
' #btn-del ': function () {//do something},
' #btn-edit ': function () {//do something}
} ,
mouseenter:{
' #btn-abc ': function () {//do something},
}
});
Is it much nicer to write, (coffee) is a custom function, can you write this function yourself? , but if the binding function is longer, the sense code looks a little messy, and the comments
Copy Code code as follows:
$ (' #btnContainer ')
. On (' Click ', ' #btn-add ', function () {})
. On (' Click ', ' #btn-del ', function () {})
. On (' Click ', ' #btn-edit ', function () {});
This kind of writing also avoids the two disadvantages mentioned above, and looks not disorderly.
