javascript - javascript表单不起作用

Question

我试图创建一个 javascript 表单，但我无法让它工作。出现的错误是

• 邮政编码应由字母和数字组成：
• 地址应该是字母数字：

• 请将每本杂志限制在 500 份或更少

  函数 display() { var totprice; var fname、lname、fullname、addr、postocde、电子邮件、电话、lstitem、数量、性别；var prditem1，prditem2，prditem3，2012 年夏季，2012 年秋季，2012 年冬季，totqty；var orddate; fname = document.form1.fname.value; lname = document.form1.lname.value; //全名 = fname + " " + lname; 性别 = document.form1.gender.value; addr = 文档.form1.address.value; 邮政编码 = document.form1.address.value; 电子邮件 = document.form1.email.value; 电话 = document.form1.telephone.value; prditem1 = document.form1.summer.value; prditem2 = document.form1.autumn.value; prditem3 = document.form1.winter.value; summer2012 = parseInt(document.form1.summer2012.value); 秋季 2012 = parseInt(document.form1.autumn2012.value); Winter2012 = parseInt(document.form1.winter2012.value); totqty = 2012 年夏季 + 2012 年秋季 + 2012 年冬季；orddate = 新日期（）；dispdate = orddate.getMonth() + 1 + "-" + orddate.getDate() + "-" + orddate.getYear(); var alertmsg = ''; var 字母 = /^[a-zàâçéèêêëîïôûùüÿñ-]*$/i var 字母数字 = /^[a-zA-Z0-9/./,/-/\n]+$/; var addrtxt = addr.replace(/(\x0a\x0d|\x0d\x0a)/g, "\n"); var chkpostcode = /^((GIR 0AA)|((([A-PR-UWYZ][A-HK-Y]?[0-9][0-9]?)|(([A-PR-UWYZ] ][0-9] [A-HJKSTUW])|([A-PR-UWYZ][A-HK-Y][0-9][ABEHMNPRV-Y]))) [0-9][ABD-HJLNP -UW-Z]{2}))$/ var chktelephone = /^0\d{9,10}$/ var chkEmail = /^.+@.+..+$/ var chkquantity = /^([1 -9]?\d|[1-4]\d{2}|500)$/ if (chkEmail.test(email) == false) { alertmsg = alertmsg + " gender1) { alertmsg = alertmsg + "请选择您的性别\n" } if (((document.form1.summer.checked) && (summer2012 <= 0)) || ((document.form1.autumn.checked) && ( fall2012 <= 0)) || ((document.form1.winter.checked) && (winter2012 <= 0))) { alertmsg = alertmsg + "请输入数量" + "\n"; } else if (((!document.form1.summer.checked) && (summer2012 > 0)) || ((!document.form1.autumn.checked) && (autumn2012 > 0)) || ((!document.form1 .winter.checked) && (winter2012 > 0))) { alertmsg = alertmsg + "请选择产品" + "\n"; } var f = document.form1; 如果 (!f.summer.checked && !f.​​autumn.checked && !f.​​winter.checked) { alertmsg = alertmsg + " 数量[1] = parseInt(document.form1.autumn2012.value); 数量[2] = parseInt(document.form1.winter2012.value); for (i = 0; i < 3; i++) { totprice = totprice + 数量[i] * price[i]; } 返回（总价）；} }

谁能建议我做错了什么？任何帮助将不胜感激。谢谢

修改这些：

脚本

var alphanumeric = /^[a-zA-Z0-9\.\,\-\n]+$/;

var quantity = new Array();
 quantity[0] = parseInt(document.form1.summer2012.value);
 quantity[1] = parseInt(document.form1.autumn2012.value);
 quantity[2] = parseInt(document.form1.winter2012.value);
 if (quantity[0] > 500 || quantity[1] > 500 || quantity[2] > 500) {
     alertmsg = alertmsg + "Please limit each magazine to 500 copies or less:" + "\n";
 }

HTML

<td colspan="2"><textarea name="address" cols="30" rows=5 col=40 wrap=soft></textarea>
