regex - How to extract floating point value from string in javascript? -


how extract value "-1.23" following string using js regex?

"hello-sdvf-1.23 23 4"

this code extracts "-1"

("hello-sdvf-1.23 23 4").match(/[-]\d+|\d+/)[0];

you need define pattern match decimal part also.

string.match(/-?\d+\.\d+/)
