[英]Why is my form just refreshing the page?
更新:我有電子郵件形式的ID,仍然有相同的問題。
我有一個表單,提交時應該彈出並顯示一個顏色框,但是代碼打開了顏色框,但是眨眼間頁面就會刷新嗎?
這是我的代碼:
<html data-wf-page="546cd4ede4d" data-wf-site="5d0115c4ca7148">

您忘記將事件變量e
作為參數傳遞來提交回調:
$("#email-form").submit(function(e){ //Here
requestTruckWarning(); // creates a colorbox
e.preventDefault(); // trying to prevent page from refreshing but never hits this breakpoint?
});
在回調函數中,您缺少傳遞的參數e
(事件對象):
$('#email-form').submit(function (e) {
requestTruckWarning() // Creates a colorbox
e.preventDefault() // This now works, because `e` exists
})
此外,似乎其他一些答案(向Jai致謝 )指出, #email-form
並未引用文檔中的元素。 在上面的代碼成功運行之前,必須先解決該問題。
您的form
沒有任何名為#email-form
ID。 添加ID屬性:
<form id='#email-form'>
或更改選擇器:
$('form').submit(function(){
並且還提到了其他答案,您必須在Submit回調中將e
作為事件傳遞。
$('form').submit(function(e){ // <-------here
如上所述,還必須進行其他兩個更改。
實際上,這里有兩個問題。 正如@Jai所說,您沒有為表單設置id屬性,因此jQuery正在尋找id ='email-form'的元素,卻一無所獲,因此代碼無法執行。 即使它確實執行,也不會停止表單提交,因為在使用e.preventDefault時,在這種情況下,“ e”是事件對象,這是您需要傳遞給事件的東西處理程序。 將id添加到for中,然后像下面這樣更改事件處理程序的聲明:
$("#email-form").submit(function(e){
