我试图将每个title属性获取到输入标签的值中,但是我尝试了很多方法,但是所有尝试都失败了,我什至尝试使用for()循环。
例如这是我的代码,然后添加javascript
<div class="all">
<div class="myOtherClass">
<a class="getTitle test" href="#" Title="i want grab this title">click me to change</a>
</div>
<div class="myOtherClass">
<a class="getTitle test" href="#" Title="i want grab this too">click me to change</a>
</div>
<div class="myOtherClass">
<a class="getTitle test" href="#" Title="same at 2 other">click me to change</a>
</div>
<div class="Otherclass">
<input class="myInput" type="button" value=""/>
</div>
</div>
这就是我试图做的
let getTitle = document.querySelectorAll('.getTitle').forEach((f) => {
f.addEventListener('click', function() {
document.querySelectorAll('.all').forEach(item =>{
let button = item.querySelector('.getinput')
let a = item.querySelectorAll('.test');
for(let i=0; i < a.length; i++){
let atitle = a[i];
button.value = atitle.title;
}
})
})
})
这是我希望我的代码在添加javascript后执行的操作
当我单击第一个标签时,将返回输入值为
<input class="myInput" type="button" value="i want grab this title"/>
当我单击第二个标签时,该标签将返回该值
<input class="myInput" type="button" value="i want grab this too"/>
但是我的结果就是这样
当我单击第一个标签时,返回输入值
<input class="myInput" type="button" value="i want grab this title"/>
当我单击第二个标签时,返回第一个标签的相同值
<input class="myInput" type="button" value="i want grab this title"/>
有没有办法解决这个解决方案?

您可以在每个锚标记上使用事件侦听器,并通过 ID 设置输入的值,您需要相应地对其进行更改:
const elements = document.getElementsByClassName('getTitle')
const input = document.getElementById('[change_this]')
Array.from(elements).forEach(a => {
a.addEventListener('click', (el) => {
input.value = el.target.title
})
})
<div class="all">
<div class="myOtherClass">
<a class="getTitle test" Title="i want grab this title">click me to change</a>
</div>
<div class="myOtherClass">
<a class="getTitle test" Title="i want grab this too">click me to change</a>
</div>
<div class="myOtherClass">
<a class="getTitle test" Title="same at 2 other">click me to change</a>
</div>
<div class="Otherclass">
<input id="[change_this]" class="myInput" type="button" value="" />
</div>

从可以理解的内容到您的操作:
old string: allOf(withId(someinfo), withContentDescription("Text"))
new string: allOf(withId(someinfo))
document.querySelectorAll('.getTitle').forEach( Z_elm => {
Z_elm.addEventListener('click', function () {
document.querySelector('.myInput').value = this.title;
// or : (in your real code)
// document.querySelector('#myModal .getinput').value = this.title;
})
})
a {cursor: pointer;}
