以下代码允许用户点击按钮并拒绝好友请求。即使在页面上显示多个结果,它也能正常运行,因为它使用wrapper.children('.decline').click(function() {
来定位正确的结果。
发生这种情况后,以下$( "#containerFriends" ).load("friends.html #containerFriends" );
应刷新页面,以便显示最新结果。但是,即使结果仍然存在,也会显示完全空白的页面。如果我手动刷新页面,则会显示正确的结果。
我不确定下面有什么问题以及造成这种问题的原因是什么?
mainQuery.find({
success: function(results) {
var friends = [];
for (var i = 0; i < results.length; i++) {
friends.push({
imageURL: results[i].get('toUser').get('pic'),
username: results[i].get('toUser').get('username'),
userId: results[i].get('toUser').id,
status: results[i].get('status'),
// Saves the object so that it can be used below to change the status//
fetchedObject: results[i]
});
}
var select = document.getElementById("FriendsConnected");
$.each(friends, function(i, v) {
var opt = v.username;
var el = document.createElement("option");
el.textContent = opt;
el.value = opt;
select.appendChild(el);
})
$('#containerFriends').empty();
$('#containerFriendsConnected').empty();
_.each(friends, function(item) {
var wrapper = $('<div class="portfolio-item-thumb one-third"></div>');
wrapper.append('<img class="responsive-image friendImgOutline" src="' + item.imageURL + '" />' + '<br>');
wrapper.append('<div class="tag">' + item.username + '</div>');
wrapper.append('<div type="button" class="btn btn-danger mrs decline">' + 'Unfriend' + '</div>');
$('#containerFriends').append(wrapper);
//The following lets the user accept or decline a friend request by changing the status the status from Pending to Declined/////
wrapper.children('.decline').click(function() {
$(".decline").click(function() {
item.fetchedObject.set("status", "Rejected");
$( "#containerFriends" ).load("friends.html #containerFriends" );
item.fetchedObject.save(null, {
success: function(results) {
console.log("REJECTED");
},
error: function(contact, error) {
// The save failed.
// error is a Parse.Error with an error code and description.
alert("Error: " + error.code + " " + error.message);
}
});
});
});
});
},
error: function(error) {
alert("Error: " + error.code + " " + error.message);
}
});
答案 0 :(得分:0)
我实际上是通过再次调用该函数来解决这个问题,然后确保数据是最新的并刷新页面。我认为问题是$('#containerFriends').append(wrapper);
在用户.click
