是否有理由爲什麼我的Ajax調用不會在if語句內工作?我可能在這裏做了一些根本性的錯誤,因爲我對JS或Ajax沒有太多的經驗。由於JQuery Ajax調用不工作If語句
工作js函數是:
function filter(varType, varValue) {
var $products = $('#products');
$.getJSON($SCRIPT_ROOT + '/filterSize/' + varValue)
.success(function (data) {
$products.empty(); // clear html from container
var elt0 = '<div class="page-content"><h1 id="shoes">Shoes</h1></div>';
$products.append(elt0);
if (Object.keys(data.shoes).length === 0) {
none = '<span class="noresults">No results</span>';
$products.append(none);
}
else {
var numItems = (Object.keys(data.shoes).length);
for (index = 0; index < numItems ; ++index) {
var elt1 = Flask.url_for("static", {"filename": data.shoes[index].img1});
var elt2 = '<div id="item" class="col-md-4"><div class="products"><a href="shop/item/' + data.shoes[index].id + '"><h5>' + data.shoes[index].name + '</h5><img src="' + elt1 + '" alt="" width="200px" height="125px"></a></div>';
$products.append(elt2);
}
}
});
}
但如果我這樣做,它突然停止工作:
function filter(varType, varValue) {
var $products = $('#products');
var x = 5
var y = 6
if (y > x) {
$.getJSON($SCRIPT_ROOT + '/filterSize/' + varValue)
}
.success(function (data) {
$products.empty(); // clear html from container
var elt0 = '<div class="page-content"><h1 id="shoes">Shoes</h1></div>';
$products.append(elt0);
if (Object.keys(data.shoes).length === 0) {
none = '<span class="noresults">No results</span>';
$products.append(none);
}
else {
var numItems = (Object.keys(data.shoes).length);
for (index = 0; index < numItems ; ++index) {
var elt1 = Flask.url_for("static", {"filename": data.shoes[index].img1});
var elt2 = '<div id="item" class="col-md-4"><div class="products"><a href="shop/item/' + data.shoes[index].id + '"><h5>' + data.shoes[index].name + '</h5><img src="' + elt1 + '" alt="" width="200px" height="125px"></a></div>';
$products.append(elt2);
}
}
});
}
因爲它是無效的javascript,您會在開發人員工具控制檯中看到的東西 - 您在if' – Suever
停止工作之後的行中丟失了一個分號 - 您得到了哪些錯誤 –
