I am getting those is an array of strings. 我得到的是一个字符串数组。 I need to check if the string contains the size
130x130
in it. 我需要检查字符串是否包含
130x130
的大小。 How can it be done? 如何做呢?
var str = 'http://mysite.com/audio/display%20image/130x130%20jpeg/5755285.jpg';
var search = '130x130';
str.indexOf(search);
If it returns anything but -1 the string has been found: 如果它返回除-1之外的任何内容,则找到该字符串:
if (str.indexOf(search) > -1) {
// Your image contains 130x130
} else {
// Your image does not contains 130x130
}
