Js: two methods to delete the specified Element in the Array

The following section describes how to delete the specified elements in an Array by js. I think this is quite good. Now I will share it with you and give you a reference. Let's take a look at the content of this section:

Js deletes the specified Element in the Array.

Method 1,

/** Method: Array. remove (dx) refactored array through traversal * function: delete array elements. * parameter: dx deletes the subscript of an element. */Array. prototype. remove = function (dx) {if (isNaN (dx) | dx> this. length) {return false;} for (var I = 0, n = 0; I
 
  
   
  

  
Method 2,
  
/** Method: Array. baoremove (dx) * function: delete array elements. * parameter: dx deletes the subscript of an element. * return value: Modify the array on the original array. */Array. prototype. baoremove = function (dx) {if (isNaN (dx) | dx> this. length) {return false;} this. splice (dx, 1);} B = ['1', '2', '3', '4', '5']; alert ("elements: "+ B +" \ nLength: "+ B. length); B. baoremove (1); // Delete alert ("elements:" + B + "\ nLength:" + B. length );
  

  
The above two methods for js to delete the specified elements in the Array are all shared by the editor. I hope to give you a reference and support for PHP.
