Javascript array retrieval extension and javascript Array Retrieval

Paste the code first. Let's take a look

/** Method: easySelect (name, value) * function: simple search for an object * parameter: name is the field name, value field value (array) * return: A group of arrays, or an Array object */Array. prototype. easySelect = function (name, value) {var _ array = new Array (); for (var I = 0; I <this. length; I ++) {if (this [I] [name] = value) {_ array [_ array. length] = this [I] ;}} if (_ array. length = 1) {return _ array [0];} return _ array ;}

It is usually used for an array of imitation objects. Take the data of a field whose value is xx.

For example, we have an array with a name. We can use

Var _ array = xxxxxxxxxxxxxxxxxxx;

Var _ zhangsan = _ array. easySelect ("name", "Zhang San ");

If it is a class information data. Another class also has James. We can even use it like this:

Var _ zhangsan = _ array. easySelect ("name", "Zhang San"). easSelect ("classType", 1 );
