How to handle escape characters in WeChat applet

在微信小程序中有两种处理转义字符的方法,分别是官方API调用和通过js文件来实现。下面我们就来一起看看这两种方法。

1.官方API调用

这种方式,我们直接在wxml布局文件中,直接调用相关特殊符号的转义字符会无效,原因是小程序的text文本控件的decode属性没有打开导致的,看下文档说明:

从文档中,我们可以发现,decode属性默认为false,不会解析我们的特殊字符,我们通过设置decode属性为true,并且调用其转义字符即可实现该特殊字符的显示。

<text class=&#39;dialog-close&#39; decode=&#39;true&#39;>< 返回</text>
Copy after login

通过上述代码即可实现 < 返回 的效果。

2.通过JS文件来实现

除了上面的实现方法,针对一些特殊字符我们还可以通过wxml与JS文件相结合的方式来实现。
首先,在wxml文件中对text文本控件做如下设置:

<text class=&#39;dialog-close&#39;>{{dialogback}}</text>
Copy after login

然后,我们在JS文件的data中设置其文本内容:

data: {
    dialogback:"< 返回",
    //... 其他配置
  }
Copy after login

通过这种方式也可以实现
