如何將formSingleSelect谷傳給js函數

<script type="text/javascript"> 

function myfunction(var id){ 
    alert("hi"+id); 
} 

<@spring.formSingleSelect path="LoginIDForm.ID" options=userIDs attributes='onChange="myfunction();"'/> 

Answer 1

我相信這將工作：

<@spring.bind path="LoginIDForm.ID" /> 

<script type="text/javascript"> 
    function myfunction(var id){ 
     alert("hi" + id); 
    } 
</script> 

<@spring.formSingleSelect path="LoginIDForm.ID" options=userIDs 
    attributes='onChange="myfunction(\'${spring.status.expression}\');"'/> 

基本上<@spring.formSingleSelect path="LoginIDForm.ID" />是這樣做的簡寫：

<@spring.bind path="LoginIDForm.ID" /> 
<select name="${spring.status.expression}"> 

</select> 

${spring.status.expression}持有的價值你需要。
