我想調用一個函數（函數showquiz（））在jQuery中，但它似乎就像它激活的功能馬上。目標是在將draggable_ts拖放到可拖放之後顯示測驗。這是我上傳所有內容的鏈接。 http://ceruleanlab.com/prozzle/prozzle.php。這是我的代碼。調用與jQuery的函數
function dragItem_ts() {
$(function() {
$("#draggable_ts, #draggable-nonvalid").draggable();
$("#droppable").droppable({
accept: "#draggable_ts",
drop: function(event, ui) {
$(this)
.addClass("ui-state-highlight")
.find("p")
.html("Correct!")
.alert("I am an alert box!");
}
}
);
}
);
showquiz();
}
function dragItem2() {
showquiz();
$(function() {
$("#draggable2, #draggable-nonvalid").draggable();
$("#droppable2").droppable({
accept: "#draggable2",
drop: function(event, ui) {
$(this)
.addClass("ui-state-highlight")
.find("p")
.html("Correct!");
}
});
});
}
function tabulateAnswers() {
// initialize variables for each choice's score
// If you add more choices and outcomes, you must add another variable here.
var c1score = 0;
var c2score = 0;
var c3score = 0;
var c4score = 0;
// get a list of the radio inputs on the page
var choices = document.getElementsByTagName('input');
// loop through all the radio inputs
for (i=0; i<choices.length; i++) {
// if the radio is checked..
if (choices[i].checked) {
// add 1 to that choice's score
if (choices[i].value == 'c1') {
c1score = c1score + 1;
}
if (choices[i].value == 'c2') {
c2score = c2score + 1;
}
if (choices[i].value == 'c3') {
c3score = c3score + 1;
}
if (choices[i].value == 'c4') {
c4score = c4score + 1;
}
// If you add more choices and outcomes, you must add another if statement below.
}
}
// Find out which choice got the highest score.
// If you add more choices and outcomes, you must add the variable here.
var maxscore = Math.max(c1score,c2score,c3score,c4score);
// Display answer corresponding to that choice
var answerbox = document.getElementById('answer');
if (c1score == maxscore) { // If user chooses the first choice the most, this outcome will be displayed.
answerbox.innerHTML = "You are correct" }
if (c2score == maxscore) { // If user chooses the second choice the most, this outcome will be displayed.
answerbox.innerHTML = "The correct answer is [email protected]"}
if (c3score == maxscore) { // If user chooses the third choice the most, this outcome will be displayed.
answerbox.innerHTML = "The correct answer is [email protected]"}
if (c4score == maxscore) { // If user chooses the fourth choice the most, this outcome will be displayed.
answerbox.innerHTML = "The correct answer is [email protected]"}
// If you add more choices, you must add another response below.
}
// program the reset button
function resetAnswer() {
var answerbox = document.getElementById('answer');
answerbox.innerHTML = "Your result will show up here!";
}

var e = document.getElementById('wrapper');
e.style.display="block";

那麼，移動showquiz（）;在你的drop事件處理程序中......代碼不會按照你想要的順序神奇地執行，你需要根據你的特定順序進行編碼。 – Adriani6
是否這樣？函數dragItem_ts（）{（function（）{（「#draggable_ts，＃draggable-nonvalid」）.draggable（）; $（「#droppable」）.droppable（）{#draggable_ts「， 下降：函數（事件，UI）{$ （本） .addClass（ 「UI狀態高亮」） .find（ 「p」）。html的 （ 「正確！」） .alert（」我是一個警告框！「）; .showquiz（）;} } ）;} ）; } –
正確，你有一個「。」在你的showquiz（）之前，你需要刪除它。 – Adriani6
