Answer 1

Do it like this:

(像这样做：)

var value = $("#text").val(); // value = 9.61 use $("#text").text() if you are not on select box...
value = value.replace(".", ":"); // value = 9:61
// can then use it as
$("#anothertext").val(value);

And also there are a lot of answers here that would best fit to any same situation as this.

(而且这里有很多答案最适合这种情况。)

You, as a developer, need to know which is which.

(作为开发人员，您需要知道哪个是哪个。)

Replace all occurrences(替换所有出现的事件)

To replace multiple characters at a time use some thing like this: name.replace(/&/g, "-") .

(要一次替换多个字符，请使用以下命令： name.replace(/&/g, "-") 。)

Here I am replacing all & chars with - .

(在这里，我用-替换所有&字符。)

g means "global"

(g表示“全球”)

Note - you may need to add square brackets to avoid an error - title.replace(/[+]/g, " ")

(注意 - 您可能需要添加方括号以避免错误 - title.replace(/[+]/g, " "))
