How Can I require a Minimum Quantity on an e-commerce Form? 如何在电子商务表格上要求最低数量？

I am using a Mal's Cart form, and have a Price Break, but I want to Require my customers to have a minimum of 15 units. 我正在使用Mal的购物车表格，并且有一个价格优惠，但我想要求我的客户最少拥有15个单位。

I tried adding this to the existing javascript validate function from Serif WebPlus X6), It does not work.: 我尝试将其添加到Serif WebPlus X6的现有javascript验证函数中），它不起作用。

if('qty1'>=15) {return true;} else{ alert("Please enter Minimum Order of 15.") return false;}

Answer 1

You're comparing a string to the number 15, not the value in the field labeled 'qty1'. 您正在将字符串与数字15进行比较，而不是标记为“ qty1”的字段中的值。 Take a look at the conditional checks in the lines above yours. 在您上方的行中查看条件检查。 You likely need something like this: 您可能需要这样的东西：

if( parseInt( form.elements['qty1'].value ) >=15) {return true;} 
else{ alert("Please enter Minimum Order of 15."); return false;}
