我遵循了一些在线说明和一些关于突出显示单词的现场推荐,但我还没有得到任何展示。我还应该提一下,我没有在控制台中收到任何错误消息。
这里是.js:
let createWordElems = function() {
for (var i = 0; i <= 54; i++) {
var singleWord = document.createElement('span') // creating 'p' element, calling it singleWord
singleWord.innerHTML = " " + shuffledWords[i]; // setting the content of the first word
singleWord.addEventListener("click", clickFunc);
// set onClick event for word
var giantArrayElement = document.querySelector('.giant-array') // selecting .giant-array and storing it in var
giantArrayElement.appendChild(singleWord); // appending singleWord to giantArrayElement
}
}
createWordElems();
///// ======== ////// HIGHLIGHT ///// ======== //////
function highlight() {
var selectSpan = document.querySelector('span')
selectSpan.addEventListener("mouseover", function(evt) {
evt.target.style.backgroundColor = "#ebce8e";
});
selectSpan.addEventListener("mouseout", function(evt) {
evt.target.style.backgroundColor = "#473611";
});
}
highlight();
更新
window.addEventListener('onload',function() {
function highlight() {
var selectSpan = document.querySelector('span')
selectSpan.addEventListener("mouseover", function(evt) {
evt.target.style.backgroundColor = "#ebce8e";
});
selectSpan.addEventListener("mouseout", function(evt) {
evt.target.style.backgroundColor = "#473611";
});
}
highlight();
});
答案 0 :(得分:2)
.addEventListener
函数通常有点棘手,因为它通常仅在元素已完全加载时才有效。要避免此问题,您应将highlight
功能放在
window.addEventListener('onload',function(){
//your function here
}
