如何在 jquery/javascript 中剪切包含“map”的字符串

Question

Does anyone know how can I cut a string that contain "map" in jquery/javascript

Example: If i have a string

var stringName = "abc mapTest bbc";

How Can I cut the string by result only mapTest?

NOTE: like assume the stringName is not the fixed value, it could change to "mapTest asdasd asdd", "asdasd asfffd mapTest" and so on. and the "mapTest" will keep changing (eg mapTest1, mapTest, mapTest5 and so on)

Answer 1

I don't know if you want to remove mapTest (or mapZZPQ or whatever), or return only mapTest when you find map . Here is code to do either:

var stringName = "123 abcmapdef 456";  // sample input

var hasMap = stringName.match(/\b\w*map\w*\b/);           // returns "abcmapdef"          
var hasNoMap = stringName.replace(/\b\w*map\w*\b/g, "");  // returns "123  456"

If you only want to match "map" at the beginning of word, remove the first \w* from the pattern, ie /\bmap\w*\b/ .

Answer 2

Given:

var stringName = "abc mapTest bbc";
var m = stringName.match(/\bmap\w+\b/);

ie match a word boundary, "map" followed by one or more[*] alphanumerics, and another word boundary.

The result you want ("mapTest") will be in

m[0]

When there's a match, String.match() returns an array, the first element of which is the matched value. If there's no match it'll return null instead.

[*] if "map" on its own should also match then change the + in the regexp to * .

Answer 3

You want something like this:

var result = stringName.split(" ");
var mapTest = result[1];

Hope that helps.

Answer 4

var stringName = "abc mapTest bbc"; 

var patt1=/mapTest/gi;

var result = stringName.match(patt1);
