我试图调整这个测量和计算地毯的形式,表格只允许你选择宽度4米或5米,你想要的长度和价格范围,但继承人我的问题,我试图让它成为一个如果宽度为5米且价格范围超过9.99
,则会弹出警告框function validateForm() {
var x = document.forms["quickestimate"]["width"].value;
var p = document.forms["quickestimate"]["pricerange"].value;
if (x == null || x == "5") {
// your allowed 5m wide just under 9.99
return true;
} else if (p == null || p >= "9.99"){
alert("Can't have 5m Wide and over £9.99");
return false;
}
}
我出错的任何想法?
答案 0 :(得分:0)
function validateForm() {
var x = document.forms["quickestimate"]["width"].value;
var p = document.forms["quickestimate"]["pricerange"].value;
if ((x == "5") && (p >= "9.99")) {
// your allowed 5m wide just under 9.99
return true;
} else {
alert("Can't have 5m Wide and over £9.99");
return false;
}
