如何分割在JavaScript字符串？

例如str = "this is part 1 one wall this is part 2 "
現在我想要分割由字分離在2份STR wall

所以想輸出是：

st1 ="this is part 1 " 
st2 ="this is part 2 " 

Answer 1

var str1 = "When I say wall I want to split"; 
var chunks = str1.split("wall"); 

alert(chunks[0]); /* When I say */ 
alert(chunks[1]); /* I want to split */ 

Answer 2

var s = str.split("wall"); 
var st1 = s[0]; 
var st2 = s[1]; 

Answer 3

var parts = str.split('wall '); 

var st1 = parts[0]; 
var st2 = parts[1]; 

Answer 4

String.split

Answer 5

只是爲了完整起見，我將添加一個正則表達式回答：

var splits = str.split(/wall /); 
alert("'"+splits[0]+"'"); //'this is part 1 ' 
alert("'"+splits[1]+"'"); //'this is part 2 '
