[英]Javascript function runs only once
在一個php類中,我正在定義一個表,該表顯示了需要聯系的客戶列表。 在第7列中,我集成了一個復選框,因此當用戶呼叫客戶端時,他/她會選中該復選框。
問題是JS函數第一次運行,然后第二次運行,它說:default.php?page = _PhoneBankingP1:1未被捕獲的ReferenceError:未定義contact(…)
下面列出了正在使用的模塊:
public function phonebank($townCode,$streetCode){
$query = "SELECT clientId, clientFirstname1, clientLastname1, clientAddress, ";
$query .= " clientMailshot, clientPhone1, clientMobile1, clientContacted, min(clientDoB) ";
$query .= "FROM _clients ";
$query .= "WHERE _clients.streetCode = '{$streetCode}' and ";
$query .= " _clients.townCode = '{$townCode}' and ";
$query .= " _clients.GE = 'Y' ";
$query .= "GROUP BY clientAddress ";
$result = $this->db->query($query);
$output = "";
if ( $result->num_rows > 0 ){
$output .= "<div class='alert alert-info'><strong>Information!</strong> All the residents shown below have been extracted from the last Electoral Register.</div>";
$output .= "<table class='table table-striped' style='font-size:10pt;' id='myTable' >";
$output .= "<thead>";
$output .= "<tr>";
$output .= "<th>ID #</th>";
$output .= "<th>Name</th>";
$output .= "<th>Address</th>";
$output .= "<th>T</th>";
$output .= "<th>Phone</th>";
$output .= "<th>Mobile</th>";
$output .= "<th class='text-center'>Contacted</th>";
$output .= "</tr>";
$output .= "</thead>";
$output .= "<tbody>";
while ( $record = mysqli_fetch_array($result, MYSQLI_ASSOC)){
$output .= "<tr>";
$output .= "<td><a href='default.php?page=_clientDetails&id=".$record['clientId']."&mode=edit' style='color: #000;'><span class='pb-clientId'>".$record['clientId']."</span></a></td>";
$output .= "<td><span class='pb-fullname'>".$record['clientFirstname1']." ".$record['clientLastname1']."</span></td>";
$output .= "<td>".$record['clientAddress']."</td>";
$output .= "<td>".$record['clientMailshot']."</td>";
$output .= "<td>".$record['clientPhone1']."</td>";
$output .= "<td>".$record['clientMobile1']."</td>";
// Makes a checkbox selected
if ( $record['clientContacted'] == 'Y'){
$optContacted = ' checked ';
} else {
$optContacted = '';
}
//$output .= "<td class='text-center' ><button id='btn-contacted-".$record['clientId']."' onclick='street.clientContacted("{$record['clientId']}","{$record['clientContacted']}")' class='btn btn-success'>Contacted</button></td>";
$output .= "<td align='center'>";
$output .= "<input type='checkbox' id='col7-".$record['clientId']."' onclick='contacted("".$record['clientId']."");' value='1' ".$optContacted." />";
$output .= "</td>";
$output .= "</tr>";
}
$output .= "</tbody>";
$output .= "</table>";
$output .= "<br/>";
echo $output;
} else {
echo "No Clients Found in this street";
}
}
然后,更新MYSQL所需的測試JS函數為:
function contacted(id) {
var clientId = id;
var col7 = "col7-"+clientId;
var col7value = $("#"+col7).is(':checked');
var data = id+"\n"+col7+"\n"+col7value;
alert(data);
//Read checkbox state
if (col7value =='false'){
contacted = 'N';
} else {
contacted = 'Y';
}
$.ajax({
type: "POST",
url: "_backend/_core/_database/update_Phonebank.php",
data: {
"id": clientId,
"contacted": contacted
},
dataType: "text",
success: function(data){
}
})
}
如果您能幫助我確定第二次不讀取該功能,將不勝感激。
您定義一個函數:
function contacted(id) {
//...
}
但是在該函數中,您使用一個值覆蓋了該函數:
contacted = 'N';
因此,下一次您嘗試調用contacted()
您將嘗試調用字符串,就好像它是一個函數一樣。
為您的變量指定唯一的名稱:
var wasContacted = '';
//...
wasContacted = 'N';
// etc.
這樣,您就不會覆蓋不想覆蓋的內容。
此外,使用var
關鍵字聲明變量將在特定范圍內(例如在該函數內)定義變量,而不僅僅是將其放在window
對象上。 (您可以在不同的作用域中使用相同名稱的變量,而不會互相影響。)
