這個驗證和重定向的問題出現在輸入時間短於5位數字時(它應該是5纔有效)。如果它的5,它確定用戶被重定向,因爲它應該是。正如我所說,問題出現時,它無效(短於5)。如果你能告訴我如何解決這個問題,我會很感激!先謝謝你們。這裏是代碼:Javascript表單驗證和重定向
<script type="text/javascript">
function redirect(){
var zip_c = document.myform.tx1.value;
var sid = document.myform.sid.value;
if ((myform.tx1.value.length == 5) || (myform.textfielda.value.length > 20)){
/* if (zip_c == "")
{
return false;
}
*/
var redirect = "http://www.yourcarinsurancefinders.com/lowest-rates/quotes/ppv_hc01/src/results/index.php?zip="+ zip_c+"&sid="+sid; //Edint redirection link here, but dont change '?zip="+ zip_c'
window.open(redirect,'blank');
}
if (myform.tx1.value == ""){
document.getElementById('valid_text').innerHTML = "Please Enter A Valid Zip Code.";
return false;
}
if ((myform.tx1.value.length < 5) || (myform.textfielda.value.length > 20) || (myform.tx1.value.length == 0))
{
document.getElementById('valid_text').innerHTML = "Please Enter A Valid Zip Code.";
return false;
}
return false;
}
</script>
,這裏是我的形式:
<form onSubmit="return redirect();" id="myform" name="myform" method="" action="">
<div id="tx_a"><div class="inText">Zip Code:</div><input type="text" class="numeric" name="tx1" id="tx1" maxlength="5" /></div>
<div id="button"><input type="submit" name="submit" value="" /></div>
<input type="hidden" id="sid" name="sid" value="<?php echo $sid; ?>" />
</form>
我發現我自己的解決方案:
function redirect(){
var zip_c = document.myform.tx1.value;
var sid = document.myform.sid.value;
if ((myform.tx1.value.length < 5) || (myform.tx1.value.length == 0))
{
document.getElementById('valid_text').innerHTML = "Please Enter A Valid Zip Code.";
return false;
}
if ((myform.tx1.value.length == 5) || (myform.textfielda.value.length > 20)){
/* if (zip_c == "")
{
return false;
}
*/
var redirect = "http://www.yourcarinsurancefinders.com/lowest-rates/quotes/ppv_hc01/src/results/index.php?zip="+ zip_c+"&sid="+sid; //Edint redirection link here, but dont change '?zip="+ zip_c'
window.open(redirect,'blank');
}
}
