javascript - 删除重置按钮验证

Question

我有下面的表格，一旦我们选择“Designer”，它只会显示选择“Order Number”的选项，如果选择“Order Number”，它只会显示选择“Product”的选项，其中“Product”是多选框。

假设我选择了“Designer”和“Order Number”，当我点击 Reset button 时，它正在验证它要求填写“Product” 值，提交按钮没问题，但它不应该对“重置”按钮进行验证。

我正在尝试 this但仍然无法正常工作....

这里所有的选项值都是从 php 代码中动态获取的，如下所示。

产品是多选框

<input type="reset" class="btn btn-large btn-primary" formnovalidate="formnovalidate" value="RESET"/>
