How to remove array elements by using JavaScript to Reduce the length _ javascript skills

Arrays are certainly not new to them. Some new users do not know how to remove array elements. The following is an example. The Code is as follows:

// Array removal Length Method

Var array = [];
Array [0] = "Zhang San ";
Array [1] = "Li Si ";
Array [2] = "Wang Wu ";
Array [3] = "Zhao six ";
Array [4] = "Baidu ";

Function remove (array, index ){
If (index <= (array. length-1 )){
For (var I = index; iarray [I] = array [I + 1];
}
} Else {
Throw new Error ('array index out of bounds! For function is: delete ');
}
Array. length = array. length-1;
Return array;
}


Try {
Array = remove (array, 2 );
Array = remove (array, 2 );
Alert (array. length );
Alert (array );
} Catch (e ){
Alert (e );
}
