J'ai un modal bootstrap qui contient une table d'utilisateurs. Je peux sélectionner un utilisateur à partir du tableau et en cliquant sur «enregistrer», les détails de l'utilisateur sélectionné sont affichés et je reçois une alerte indiquant «Les données ont été sauvegardées avec succès!Alerte apparaissant même si aucune sélection n'est faite dans la table
L'alerte se trouve à la fin de la méthode 'saveData()' dans mon code.
Cependant, même lorsqu'aucune ligne n'est sélectionnée à partir du tableau, lorsque je clique sur enregistrer, la même alerte 'Données enregistrées avec succès!' S'affiche toujours. Comment puis-je m'assurer que l'alerte ne s'affiche que si les détails d'une option sélectionnée sont ajoutés?
var currentPageNo = 0; // Keep track of currently displayed page
// Select button that is descendant of userList
$('#userList .prev-btn').click(function(){
userList(currentPageNo-10);
});
$('#userList .next-btn').click(function(){
userList(currentPageNo+10);
});
$('#adminList .prev-btn').click(function(){
adminList(currentPageNo-10);
});
$('#adminList .next-btn').click(function(){
adminList(currentPageNo+10);
});
function userList(pageNo) {
var resType="userList";
createTable(resType,pageNo);
}
function adminList(pageNo) {
var resType="adminList";
createTable(resType,pageNo);
}
function createTable(resType, pageNo) {
// Update global variable
currentPageNo = pageNo;
// Set visibility of the correct "prev" button:
$('#' + resType + ' .prev-btn').toggle(pageNo > 0);
// Ask one record more than needed, to determine if there are more records after this page:
$.getJSON("https://api.randomuser.me/?results=11&resType="+resType + "&pageIndex=" + pageNo, function(data) {
var $table = $('#' + resType + ' table');
$('tr:has(td)', $table).empty();
// Check if there's an extra record which we do not display,
// but determines that there is a next page
$('#' + resType + ' .next-btn').toggle(data.results.length > 10);
// Slice results, so 11th record is not included:
data.results.slice(0, 10).forEach(function (record, i) { // add second argument for numbering records
var json = JSON.stringify(record);
$table.append(
$('<tr>').append(
