格式化双内标签文本的十进制数字(Formatting decimal digits for double inside label text)

我有这行代码:

label4.Text = "(" + x1 + ", 0), (" + x2 + ",0)";

x1x2都是双精度值。 我无法用两位小数显示它们。 我知道我可以使用{0:N2}但我找不到正确的语法方式来使用它因为我想要显示的字符串中有两个值。 我应该如何编写它以使两个值( x1x2 )显示在字符串中,只有2位十进制数字?


I have this line of code:

label4.Text = "(" + x1 + ", 0), (" + x2 + ",0)";

Both x1 and x2 are double values. I cannot make them display with two decimal digits. I know that I can use {0:N2} but I cannot find right syntax way to use it because I have two values in string I want to display. How should I write it to make both values (x1 and x2) display in string with just 2 decimal digits?

最满意答案

添加到您的范围:

scope
{
  value: '=',
  controllerFunction: '='
}

在您的链接功能上,您可以致电:

   scope.controllerFunction();

然后在HTML上,当你包含你的指令时,你需要将控制器函数作为属性传递:

<edit-in-place value="something" controller-function="testar">

Add to your scope:

scope
{
  value: '=',
  controllerFunction: '='
}

And on your link function you call:

   scope.controllerFunction();

And then on the HTML, when you include your directive, you need to pass the controller function as an attribute:

<edit-in-place value="something" controller-function="testar">
