用LTR和RTL内容组合来改变负数的方向 [英] Change direction of negative number with combination of LTR and RTL content

问题描述

这是我的HTML结构：

  div {direction：rtl; } span {direction：ltr;}  

 < div& < span>امروز-2< / span> < / div>  

这是预期的结果：

如您所见， 符号应该在数字的开头。

div 的方向应该是 rtl 。

生成这样的数字：

  $ sums_value = sprintf（％+ d，$ sums_value）; 
 
 / * 
 sums_value = -2 // => -2 
 sums_value = 2 // => +2 
  

所以数字有正确的格式，但我不知道为什么会被打破输出：

解决方案

由于你的截图在不同的 span 元素中有-2，你可以是 unicode-bidi 选项：

  div {direction：rtl;} span {direction：ltr; unicode-bidi：bidi-override;}  

 < div> ; امروز< span> -2< / span>< / div>  

unicode-bidi 的一般思想是有能力更改文本的方向性的默认行为，其中有多种语言

由于您使用的是 RTL 语言，您希望 -2 出现在 LTR ， unicode-bidi：bidi-override 非常方便。

Here is my HTML structure:

div{
  direction: rtl;
}

span{
  direction: ltr;
}

<div>
  <span>امروز -2</span>
  </div>

This is expected result:

As you see, - sign should come in the beginning of the number. How can I do that?

Note: The direction of div should be rtl.

---

ٍEDIT: I generate that number like this:

$sums_value = sprintf("%+d",$sums_value);

/* 
sums_value = -2 //=> -2
sums_value = 2  //=> +2

So the number has right format, but I don't know why it will be broken in the output:

解决方案

Since your screenshot has the "-2" in a different span element you could is the unicode-bidi option on that specific span:

div{
  direction: rtl;
}

span{
  direction: ltr;
  unicode-bidi: bidi-override;
}

<div>
  امروز 
  <span>-2</span>
</div>

The general idea of unicode-bidi is to have the ability to change the default behavior of directionality of the text where you have multiple languages on the same page.

Since you are using an RTL language, and you want the -2 to appear in LTR, the unicode-bidi: bidi-override is very handy.
