我有一个表单，当提交时将数据传递给taskqueue.php，然后继续将值传递给process.php。如果在下拉列表中选择了特定值，则GAE任务队列将不会继续
继承人的下拉这就是导致问题：
<select id="year" name='year'>
<option value="0">Year End...*</option>
<option value="2013">2013</option>
<option value="2014">2014</option>
<option value="2015">2015</option>
</select>
如果我选择2015年，没有任何问题，它会继续到taskqueue.php然后processing.php和执行任务。如果我选择2014年或2013年，那么我会看到一个空白页面，其URL看起来像卡住了taskqueue.php。
如果我改变所有的下拉菜单的“价值”到2015年，那么它会继续处理任务如
<option value="2015">2013</option>
<option value="2015">2014</option>
<option value="2015">2015</option>
，世界上没有问题，只是似乎本身就是价值。
我确实有隐藏/显示下拉菜单的javascript，但我无法看到任何引用2014/2013的任何地方。
下面 FORM见代码：
<script type="text/javascript" language="javascript">
function display_Field(e){
document.getElementById('month').style.display = "none";
document.getElementById('quarter').style.display = "none";
document.getElementById('year').style.display = "none";
periodend=document.getElementById('periodend').value;
if (periodend === 'Monthly') {
document.getElementById('year').selectedIndex = 0;
document.getElementById('month').style.display = "inline";
document.getElementById('year').style.display = "inline";
document.getElementById('quarter').selectedIndex = 0;
}
if(periodend === 'Quarterly') {
document.getElementById('year').selectedIndex = 0;
document.getElementById('quarter').style.display = "inline";
document.getElementById('year').style.display = "inline";
document.getElementById('month').selectedIndex = 0;
}
if (periodend === 'Yearly'){
document.getElementById('year').selectedIndex = 0;
document.getElementById('year').style.display = "inline";
document.getElementById('month').selectedIndex = 0;
document.getElementById('quarter').selectedIndex = 0;
}
}
function validate() {
periodend=document.getElementById('periodend').value;
month=document.getElementById('month').value;
quarter=document.getElementById('quarter').value;
year=document.getElementById('year').value;
if (periodend==='0'||(periodend==='Monthly' && (month==='0'||year==='0'))||(periodend==='Quarterly' && (quarter==='0'||year==='0'))||(periodend==='Yearly' && year==='0')) {
valid_alert='';
if (periodend==='0') {
valid_alert='Please select a period end\n';
}
if (periodend==='Monthly' && (month==='0'||year==='0')) {
if (month==='0') {
valid_alert=valid_alert+'Please select a month end\n';
}
if (year==='0') {
valid_alert=valid_alert+'Please select a year\n';
}
}
if (periodend==='Quarterly' && (quarter==='0'||year==='0')) {
if (quarter==='0') {
valid_alert=valid_alert+'Please select a quarter end\n';
}
if (year==='0') {
valid_alert=valid_alert+'Please select a year\n';
}
}
if (periodend==='Yearly' && year==='0') {
valid_alert=valid_alert+'Please select a year\n';
}
alert(valid_alert);
return false;
} else {
return true;
}
}
