The function Xtool (id, MSG) {
This. Id=id;
This. MSG=MSG;
}
.

New Xtool (" x1 ", "1234567")

Then the js, how to find a object?
Can you find like this? Eval (" x1 "), the document. The getElementById (" x1 ")
But can't. How do I find?

CodePudding user response:

A custom object is not attribute search by id, only new Xtool (" x1 ", "1234567"), the return value of the access object,

CodePudding user response:

Js object different from the dom tree, js object in memory don't you return address, how are you going to use

CodePudding user response:

A single object creation can use variables to store, var xtool=new xtool (' a ', '1111');
This xtool is on behalf of the newly created object

If you want to create multiple objects can use an array to store, can also use a dictionary to store, if id is not repeated dictionary is very convenient,

For example: dic [' a ']=new Xtool (' a ', '1111');
Dic (' a ') is a new object

Understand, thank you.

Pressed by, how element to add methods, add event?
The function initMy () {
This style. Diasplay=""
.
}

Then can do this with
Adiv. InitMy ()

More events
Adiv. OnchangeStyle=function ()

With the apply or call to the caller, otherwise this point to incorrect
Or use initMy (Adiv) to invoke the function initMy (obj) {obj. Ooo. XXXX... }

The function initMy (ele) {
This. Ele=ele; 

this.init(); 
Enclosing regEvent (); 
} 
InitMy. Prototype. The init=function () {
This. Ele. Style. The display='
} 
InitMy. Prototype. RegEvent=function () {
This. Ele. Onclick=function () {} 
}
