我正在做一个简短的问答游戏,我似乎无法弄清楚哪种事件侦听器适合检测文本框中的特定字符串。这是我到目前为止的内容(仅当“ else if”部分被取出而未检测到特定字符串时才有效)
HTML:
<div id="ques1" class="ques">
<img src="img/img1.png" alt="">
<div id="btncontainer" class="btncontainer">
<input id="txtbox" placeholder="Type here"/>
<button id="go1" class="gobttn"><i>NEXT<i></button>
</div>
</div>
<div id="ques2" class="ques">
<img src="img/img2.png" alt="">
</div>
JS:
var s2 = document.getElementById('ques1')
var s3 = document.getElementById('ques2')
var b1 = document.getElementById('landbtn')
var b2 = document.getElementById('go1')
var tbox = document.getElementById('txtbox')
function Quest1To2() {
s2.style.display = 'none';
s3.style.display = 'block';
}
b2.addEventListener('click', Quest1To2)
function TxtErr() {
tbox.style.outline = '0.2em solid red';
}
b2.addEventListener('click', TxtErr)
var a1 = "NEO";
var answer = txtbox.value
if (answer == a1) {
Quest1To2();
}
else if () {
TxtErr();
}
最佳答案
当在input
处发生输入时,可以使用tbox
事件调度事件。
tbox.oninput = function(e) {
if (e.target.value == a1) {
Quest1To2();
}
else {
TxtErr();
}
}
