我有一行HTML下拉列表,每当用户选择其中一个选项时,它会通过提交表单的类调用jQuery函数。
<form id="workorderform" action="saveworkorder.php" method="post">
<select name="applicationtype" class="checkvalueonchange savevalueonchange">
<option></option>
<option value="Uplift" <?php echo ($wo['applicationtype']=='Uplift')?'selected':''; ?>>Uplift</option>
</select>
</form>
savevalueonchange
类调用
$(".savevalueonchange").change(function() {
autoSave();
});
然后调用
function autoSave() {
if($("#wostatus").val()=='open'){
$("#workorderform").submit();
}
}
将信息发布到saveworkorder.php
//remove existing chargecodes
$sql = "DELETE FROM workorderchargecodes WHERE compresscoid = '".trim($_REQUEST['formid'])."'";
mssql_query($sql, $dbconn);
//now save chargecodes
$code_prefix = 'code_';
foreach($_POST as $thisPostKey => $thisPostValue) {
if((substr($thisPostKey, 0, strlen($code_prefix)))==$code_prefix) {
if(trim($thisPostValue)!=''):
$exists=false;
$sql = "SELECT * FROM workorderchargecodes WHERE compresscoid='".trim($_REQUEST['formid'])."' AND code='".substr($thisPostKey, strlen($code_prefix), strlen($thisPostKey))."'";
$res = mssql_query($sql, $dbconn);
while($arr = mssql_fetch_assoc($res)){
$exists=true;
}
if($exists==false){
$sql = "INSERT INTO workorderchargecodes (
compresscoid,
code,
time
) VALUES (
'".trim($_REQUEST['formid'])."',
'".substr($thisPostKey, strlen($code_prefix), strlen($thisPostKey))."', '".$thisPostValue."'
)";
mssql_query($sql, $dbconn);
}
endif;
}
}
正如您所看到的,我在将数据库插入数据库之前从数据库中选择代码,并且不知何故仍然会收到重复的费用代码。我已经搞砸了几个月了,它仍然在发生。
有什么想法吗?

尝试在自动保存()中添加return false;
,如下所示:
function autoSave() {
if($("#wostatus").val()=='open'){
$("#workorderform").submit();
return false; // add here
}
}
它会阻止提交两次。

<form id="workorderform" action="saveworkorder.php" method="post" onsubmit="return false;">
<select name="applicationtype" class="checkvalueonchange savevalueonchange">
<option></option>
<option value="Uplift" <?php echo ($wo['applicationtype']=='Uplift')?'selected':''; ?>>Uplift</option>
</select>
</form>
使用此表格
它使用obsubmit="return false;"
