Question

2×的getElementById元素我不得不修改下面的代碼，包括persDonateAllocat值：

<script type="text/javascript"> 
    function doAddPersonalDonation(personaldonation, id){ 
      if(isNaN(personaldonation)){ 
       alert("Please enter only round numbers and no cents."); 
      }else{ 
       window.location = "adopt.php?action=add&personaldonation=" + personaldonation + "&id=" + id + "&all=" + persDonateAllocat; 
      } 
     } 
    </script> 

<a href=\"javascript:doAddPersonalDonation(
      document.getElementById('personaldonation').value,$id 
      )\">Add To Cart</a> 

我曾嘗試下面的代碼，但點擊該鏈接現在什麼都不做：

<a href=\"javascript:doAddPersonalDonation(personaldonation, persDonateAllocat){ 
      document.getElementById('personaldonation').value,$id; 
      document.getElementById('persDonateAllocat').value; 
      } \">Add To Cart</a> 

我加入這個，現在完美的作品：

<script type="text/javascript"> 
    function doAddPersonalDonation(personaldonation, id){ 
     var persDonateAllocat= document.getElementById('persDonateAllocat').value; 
      if(isNaN(personaldonation)){ 
       alert("Please enter only round numbers and no cents."); 
      }else{ 
       window.location = "adoptions_2.php?action=add&personaldonation=" + personaldonation + "&id=" + id + "&all=" + persDonateAllocat; 
      } 
     } 
    </script> 

<a href=\"javascript:doAddPersonalDonation(
       document.getElementById('personaldonation').value,$id 
       ) 
       \">Add To Cart</a> 

Answer 1

這個怎麼樣？ DEMO。

HTML：

<a id="myLink">Some link</a> 
<input id="personaldonation" /> 
<input id="persDonateAllocat" /> 

的jQuery：

$("#myLink").click(function() { 
    var id = 123; 
    var personaldonation = $("#personaldonation").val(); 
    var persDonateAllocat = $("#persDonateAllocat").val(); 
    window.location = "adopt.php?action=add&personaldonation=" + personaldonation + "&id=" + id + "&all=" + persDonateAllocat; 
});
