使用jquery或javascript从字符串中获取值

Question

I have string like this:-

var src=url("http://localhost:200/assets/images/eyecatcher/6/black6.png)"

And now I want to get image name ie black6.png and folder name 6 . I know there is substr function I can use but the file name and folder name will be dynamic like orange12.png and 12 etc.

How I can get these values? Please help me.

Thanks

Answer 1

You can use split method for this:

var src = "http://localhost:200/assets/images/eyecatcher/6/black6.png";
var parsed = src.split( '/' );
console.log( parsed[ parsed.length - 1 ] ); // black6.png
console.log( parsed[ parsed.length - 2 ] ); // 6
console.log( parsed[ parsed.length - 3 ] ); // eyecatcher

etc.

If the base URL is always the same you could do

var url = "http://localhost:200/assets/images/eyecatcher/6/black6.png";
var bits = url.replace("http://localhost:200/assets/images/eyecatcher/", "").split("/");
var folder = bits[0], // 6
    file = bits[1];  // black6.png

Answer 3

If your string is:

var src="http://localhost:200/assets/images/eyecatcher/6/black6.png"

Use the following:

var parts = src.split('/');
var img = parts.pop(); //black6.png
var flder = parts.pop(); //6
var sflder = parts.pop(); //eveatcher

Answer 4

You may try like this:

var str = myString.split('/');
var answer = str[str.length - 1];
var answer1 = str[str.length - 2];
var answer2 = str[str.length - 3];

Answer 5

var img_name = src.split('/')[7];
var folder_name = src.split('/')[6];

Answer 6

Using split & slice , Say like bellow

var src = "http://localhost:200/assets/images/eyecatcher/6/black6.png";
var arr = src.split('/').slice(-2) //returns ["6", "black6.png"]
arr[0] //folderName
arr[1] //filename

Answer 7

var str = "http://MachineName:200/assets/images/eyecatcher/6/black6.png";

var newStr = str.split("/");  

ubound = newStr.length;

fileName = newStr[ubound-1];
