[备忘]js表单值正则表达式验证工具

long272449358

//用法,写个提交表单的方法，提交前使用
function submitForm() {var matcher = new checkObj();matcher.add($("[name='nodePort']").val(), portMatch);matcher.add($("[name='nodeIP']").val(), ipMatch);if(!matcher.check()) return;document.cardForm.submit();}


//下面是代码，已经包含了一些常用的正则对象，没有的话自己加

//格式：var a = {""exp" : 正则表达式, "warning" : 提示信息};

//例:var numMatch = {"exp" : /^([A-Za-z0-9]+)?$/, "warning" : "请输入英文或数字！"};
