JavaScript : parse float with string prefix in both start and end

Question

如何将这个字符串转换为浮点型？ 我想要结果 900.50

case-1: var ConvertThis = '此处任意字符串 900,50 此处也任意字符串';

case-2: var ConvertThis = '此处任意字符串 900.50 此处也任意字符串';

如何做到这一点？

Answer 1

尝试以下代码:

var text = 'any string here 900,50 also any string here';
var matched = text.match(/\d+[,.]\d+/)[0].replace(',', '.');
var num = parseFloat(matched, 10);
console.log(matched);
console.log(num);

打印:

900.50
900.5
