3. Causes and Solutions

The original code is as follows

<el-progress :percentage="percentage" :color="customColor"></el-progress>

reason:

The percentage attribute value set exceeds 100, and the value range of percentage is 0-100

Solution:

When assigning the percentage attribute, just make a ternary operation judgment. The code is as follows

<el-progress :percentage="percentage>100?100:percentage" :color="customColor"></el-progress>
