JavaScript string array Conversion Function

Two custom js functions that implement mutual conversion between strings and arrays hope to be useful to you:

Copy to ClipboardReference: [www.bkjia.com] 1 function StringToArray (str, substr ){
2
3/* function: Splits a string into an Array Based on the specified string.
4 parameters:
5 str: string to be converted
6 substr: Split string
7 return value:
8. converted Array
9 */
10 var arrTmp = new Array ();
11
12 if (substr = ""){
13 arrTmp. push (str );
14 return arrTmp;
15}
16
17 var I = 0, j = 0, k = str. length;
18
19 while (I <k ){
20 j = str. indexOf (substr, I );
21
22 if (j! =-1 ){
23 if (str. substring (I, j )! = "") {ArrTmp. push (str. substring (I, j ));}
24 I = j + 1;
25} else {
26 if (str. substring (I, k )! = "") {ArrTmp. push (str. substring (I, k ));}
27 I = k;
28}
29}
30
31 return arrTmp;
32}
33
34
35 function ArrayToString (arr, str ){
36
37/* function: convert an array to a string based on the delimiter (string ).
38 parameters:
39 arr: String Array to be converted
40 str: Split string
41 return values:
42. converted string
43 */
44 var strTmp = "";
45
46 for (var I = 0; I <arr. length; I ++ ){
47 if (arr [I]! = ""){
48 if (strTmp = ""){
49 strTmp = arr [I];
50} else {
51 strTmp = strTmp + str + arr [I];
52}
53}
54}
