During ExtJS in the first half of the year, special elements in the array need to be directly deleted due to some special circumstances of the project, and the input parameters may be subscripts or array elements. So I am struggling with the following method, and I will check it later. /*** Method: Array. remove (dx) * power... syntaxHighlighter. all (); During ExtJS in the first half of the year, specific elements in the array need to be deleted directly due to some special circumstances of the project,
The input parameter may be a subscript or an array element.
So I am struggling with the following method, and I will check it later.
/**

Array. prototype. getIndexByValue = function (value ){
Var index =-1;
For (var I = 0; I <this. length; I ++ ){
If (this [I] = value ){
Index = I;
Break;
