Replace all the dots in a number
提问by s427
I'm trying to replace all dots found in a value entered by the user in an HTML form. For instance I need the entry '8.30' to be converted to '8x30'.
我正在尝试替换用户在 HTML 表单中输入的值中找到的所有点。例如，我需要将条目“8.30”转换为“8x30”。
I have this simple code:
我有这个简单的代码：
var value = $(this).val().trim(); // get the value from the form
value += ''; // force value to string
value.replace('.', 'x');
But it doesn't work. Using the console.log command in Firebug, I can see that the replace command simply does not occur. '8.30' remains the same.
但它不起作用。在 Firebug 中使用 console.log 命令，我可以看到替换命令根本没有发生。“8.30”保持不变。
I also tried the following regexp with no better result:
我还尝试了以下正则表达式，但没有更好的结果：
value.replace(/\./g, 'x');
What am I doing wrong here?
我在这里做错了什么？

replace返回一个字符串。尝试：
value = value.replace('.', 'x'); //

You have three solutions:
你有三个解决方案：
var text= "ABC.DEF.XYZ";
response = text.replace(/\./g,'x');
var text= "ABC.DEF.XYZ";
response = text.replace(new RegExp("\.","gm"),"x");
var text= "ABC.DEF.XYZ";
response = text.split('.').join('x');
