如何在javascript中提供空间或下一行功能？

Question

这是我的java脚本代码：

function for_approve(){
var approve = confirm(format_stock_id.length + 
               "&nbsp;Stock Record(s) is selected for approval.<br /> 
               Do You Want to send it for Approval");

}

它给我结果：

3 &nbsp;Stock Record(s) is selected for approval.<br />Do You Want to send it for Approval

我应该怎样做空间和新线。

Answer 1

使用\n符号：

function for_approve(){
var approve = confirm(format_stock_id.length + 
               " Stock Record(s) is selected for approval.\n 
               Do You Want to send it for Approval");

}

你可以在这里查看。在浏览器中打开控制台并写下：alert("bob\nbob");

示例

命令：

结果：

P.S。：同样的空间。您不必使用转义查询 。只需使用（简单空格）。

Answer 2

要跳转到下一行，您需要使用\ n而对于空格，无需编写＆amp; nbsp，只需编写空白字符，

function for_approve(){
var approve = confirm(format_stock_id.length + " Stock Record(s) is selected for approval.\n Do You Want to send it for Approval");
}

Answer 3

您可以在字符串中使用JS Escape字符（参考：http://www.w3schools.com/js/default.asp）：

\'  single quote
\"  double quote
\\  backslash
\n  new line
\r  carriage return
\t  tab
\b  backspace
\f  form feed

Answer 4

如果你想让句子对复数有点整洁，你可以这样做：

if (format_stock_id.length == 1) {
    var approve = confirm("1 Stock Record is selected for approval.\n 
    Do You Want to send it for Approval");
} else {
    var approve = confirm(format_stock_id.length + " Stock Records are selected for approval.\n
    Do You Want to send them for Approval");
}

这样的小事在最终产品中会产生很大的差异。

Answer 5

使用：

\xa0

空间

\n

新行

您的代码将是：

function for_approve(){
   var approve = confirm(format_stock_id.length + "\xa0 Stock Record(s) is selected for approval.\n Do You Want to send it for Approval");
}
