推荐答案

检查以下javascript函数.

Check below javascript function.

function checkdate(input){
var validformat=/^\d{2}\/\d{2}\/\d{4}

/ //Basic check for format validity var returnval=false if (!validformat.test(input.value)) alert("Invalid Date Format. Please correct and submit again.") else{ //Detailed check for valid date ranges var monthfield=input.value.split("/")[1] var dayfield=input.value.split("/")[0] var yearfield=input.value.split("/")[2] var dayobj = new Date(yearfield, monthfield-1, dayfield) if ((dayobj.getMonth()+1!=monthfield)||(dayobj.getDate()!=dayfield)||(dayobj.getFullYear()!=yearfield)) alert("Invalid Day, Month, or Year range detected. Please correct and submit again.") else returnval=true } if (returnval==false) input.select() return returnval }

/ //Basic check for format validity var returnval=false if (!validformat.test(input.value)) alert("Invalid Date Format. Please correct and submit again.") else{ //Detailed check for valid date ranges var monthfield=input.value.split("/")[1] var dayfield=input.value.split("/")[0] var yearfield=input.value.split("/")[2] var dayobj = new Date(yearfield, monthfield-1, dayfield) if ((dayobj.getMonth()+1!=monthfield)||(dayobj.getDate()!=dayfield)||(dayobj.getFullYear()!=yearfield)) alert("Invalid Day, Month, or Year range detected. Please correct and submit again.") else returnval=true } if (returnval==false) input.select() return returnval }
