在我的代碼中，我試圖從表單控件中的3個輸入中獲取數據。 但是，當我單擊提交時，不捕獲數據並重新加載頁面。 提交按預期觸發table.draw（），但輸入中的值都未被捕獲並添加到請求中。 我試圖直接在ajax塊中將值拉到提交函數中的單獨變量中。無法從我的表單中獲取數據到數據表請求
我在做什麼錯？

在ajax調用的數據元素中，它似乎只適用於靜態數據。我需要能夠動態地將參數發送到我的網址。
data: function(data) {
return $.extend({}, data, {
"dtStart" : "2/1/2017", //$('#dtStart').val(),
"dtEnd" : "2/28/2017", //$('#dtEnd').val(),
"reqID" : "451" //$('#reqID').val()
});
這是請求，請注意最後3個變量是空的。那些應該包含我的價值觀。

PHP在哪裏？ –
您的表單元素需要名稱。 –
輸入標籤的名稱屬性在哪裏？ – Shan
