Question

我有这样的字符串： -

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

现在我想要获取图像名称，即black6.png和文件夹名称6。我知道我可以使用substr函数，但文件名和文件夹名称将是动态的 orange12.png和12等。

我如何获得这些价值观？请帮帮我。

Answer 1

您可以使用split方法：

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

如果基本网址始终与您相同

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

如果你的字符串是：

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

使用以下内容：

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

Answer 4

您可以尝试这样：

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

使用split＆amp; slice，像吼声一样说话

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];

使用jquery或javascript从字符串中获取值
