我正在創建一個數學問題網站,並在一個頁面中我有一個部分,用戶單擊提交,它將檢查答案是對還是錯。Jquery單擊表單輸入未運行的事件
這裏是一個我有麻煩我的代碼的主要部分:
var newProblem = function(){
var textHide = true;
var submitTimes = 0
$("#content").append("<h2 class='middle_text'>Notice, this page is in BETA stage, improvement is still needed.</h2>")
$(".middle_text").fadeTo(1000,.8)
setTimeout(function(){$(".middle_text").fadeTo(500,0,function(){$(".middle_text").hide()})},4000);
setTimeout(function(){
var denominator = getNumbersEquivFrac.den()
var numerator = getNumbersEquivFrac.num(denominator);
var equivalent = getNumbersEquivFrac.equiv()
var problem = new equivalFrac(numerator,denominator,equivalent);
$("#content").append("<div class ='problem-choice' id='solve'>SOLVE THIS!</div>")
$("#content").append("<div class='problem-choice' id='answer'>SKIP AND GET ANSWER</div>")
$("#content").append("<div style='margin:auto; width:450px; text-align:center'><p id='question'>" + problem.printQuestion() + "</p>")
$("#content").append("<div id='instructions'></div>")
$("#question").fadeTo(750,1);
$(".problem-choice").fadeTo(750,1);
$("#solve").click(function(){
if(textHide === true){
$("#content").append("<form name='answer'><input class='problem-text' type='text' name='answer-input'><input type='button' class='problem-submit' value ='SUBMIT ANSWER'></form>");
$(".problem-text").fadeTo(300,.8)
$(".problem-submit").fadeTo(300,.8)
textHide = false
}
})
},4500)
}
newProblem();
$(".problem-submit").click(function(){
var checkAnswer = function(){
var answer = document.forms["answer"]["answer-input"].value;
if(answer === null || answer === ""){
alert("You must type in an answer.")
}
else{
submitTimes = submitTimes + 1;
if(answer !== problem.answer()){
if(submitTimes < 2){
$("#content").append("<div class='result' id='wrong'><div id='problem-des'><p>The correct answer was " + problem.answer() + "." + "</p></div><button id='next'>NEXT</button></div>");
$(".result").fadeTo(500,1)
}
}
else if(answer===problem.answer()){
if(submitTimes < 2){
alert("Correct!")
}
}
}
}
checkAnswer()
});
這就是事件是表單提交按鈕
$(".problem-submit").click(function(){
var checkAnswer = function(){
var answer = document.forms["answer"]["answer-input"].value;
if(answer === null || answer === ""){
alert("You must type in an answer.")
}
else{
submitTimes = submitTimes + 1;
if(answer !== problem.answer()){
if(submitTimes < 2){
$("#content").append("<div class='result' id='wrong'><div id='problem-des'><p>The correct answer was " + problem.answer() + "." + "</p></div><button id='next'>NEXT</button></div>");
$(".result").fadeTo(500,1)
}
}
else if(answer===problem.answer()){
if(submitTimes < 2){
alert("Correct!")
}
}
}
}
checkAnswer()
});
我不知道事實上這個事件是在一個通過代碼追加的選擇器上調用的,而不是最初在html文檔中調用的。
我試圖調用頁面上最初存在的部分的事件,它的工作。
但它不適用於這些,如果你有任何想法,請說出來。
