JQuery string contains check

2018-05-29 00:07:02

I need to check whether a string contains another string or not?

var str1 = "ABCDEFGHIJKLMNOP";
var str2 = "DEFG";

Which function do I use to find out if str1 contains str2?

你可以使用javascript的indexOf函数。

var str1 = "ABCDEFGHIJKLMNOP";
var str2 = "DEFG";
if(str1.indexOf(str2) != -1){
    console.log(str2 + " found");
}

var str1 = "ABCDEFGHIJKLMNOP";
var str2 = "DEFG";

sttr1.search(str2);

它会返回匹配的位置，如果找不到则返回-1。

请尝试：

str1.contains(str2)
