vue在v-html的html字符串中绑定事件


最近做项目,使用得vue作为基础框架。有这样一个需求,需要给返回来的富文本绑定事件,搜了一下众说纷纭。自己摸索了和总结出一套比较好用得方式。

利用JavaScript事件捕获,通过给使用v-html的标记绑定click事件,捕获到点击的标记。从而实现vue动态绑定dom元素事件的效果;

代码如下:

富文本数据:

"richTextContent": "<p class='testssss' data-innervalue='sadsadsa' data-value='{nasdlkashdashdkjsahdksd}'><span style=\"font-size: 14px;\">span>Some Wi?Fi networks are open and you can simply connect for internet access. Other Wi?Fi networks are secure and require you to enter a password. Contact the Wi-Fi network's owner for the password.p><p>To search for and connect with available Wi-Fi networks:p><ol class=\" list-paddingleft-2\"><li><p>Swipe down from the top of your screen to open <strong>quick settingsstrong> and then:p>li><ul class=\" list-paddingleft-2\"><li><p>Android 9: Touch & hold <img src=\"https://help.motorola.com/hc/images/global/qs_wifi_on_90.png\"/>.p>li><li><p>Android 8: Touch <strong>Wi Fi > More settingsstrong>p>li><li><p>Android 7: Touch <strong>Wi Fistrong>.p>li>ul><li><p>Turn Wi-Fi on <img src=\"https://help.motorola.com/hc/images/global/slider_on.png\"/>.p>li><li><p>Touch the Wi-Fi network you want to connect to.p>li><li><p>If the network is a secure one, enter the password.p>li>ol><p>Make sure you enter the password correctly. Touch <strong>Show passwordstrong> to see what you’re typing.p><p>When your phone is connected, <img src=\"https://help.motorola.com/hc/images/global/i_wifi_min.png\"/> appears in the status bar. If the connection is poor, <img src=\"https://help.motorola.com/hc/images/global/i_wifi_poor.png\"/> appears in the status bar.p>",

vue模板写法

<div class="richText" v-html="richTextContent" @click="test">div>

script方法

test (event) {
   console.log(event.target.className) // testssss
   console.log(event.target.nodeName) // p
   if (event.target.nodeName === 'p' && event.target.className === 'testssss') {
     // 获取触发事件对象的属性
     alert('a')
   }    
}

最终效果
