How to obtain text information of the current element

1. Obtain the content of the current click

&lt;li @click="problem1"&gt;
      1. &lt;span class="blue"&gt;About the use of the official account&lt;/span&gt;
      &lt;img src="../img/" alt=""/&gt;
&lt;/li&gt;

When I click on this li tag, I want to get the text in the span, I can use this method:

 problem1: function(e){
   ();
 }

That's OK

2. Chinese judgment

Notice:The character set must be correct, for example, it is all utf-8 or gbk. Otherwise, the judgment will be wrong.

The above method of obtaining text information for current elements is all the content I share with you. I hope you can give you a reference and I hope you can support me more.
