大家好,所有人都可以帮助我如何仅显示一次JSON数据,例如 我已经显示了人员编号1的信息,然后我将鼠标悬停在人员编号2的名称上,然后将其悬停回到人员编号1,而不是再次显示人员1的信息,它只会突出显示已显示的先前显示的人员信息1
这是我显示信息的代码
foreach (i = 0; i < PersonInfo.length; i++) {
if (e.target.parentNode.parentNode == PersonInfo[i])
{
index = i;
break;
//document.getElementById("rightcontainer").style.backgroundColor = "green" ;
}
}
var html += '';
html += '<div id="infocontainer">';
html += '<div class="p-image"><img src="src/images/someimage.png"/></div>';
html += '<div class="popupdetail">';
html += '<div class="p-name"> Person Name: ' + Person[index].person_name+ '</div>';
html += '<div class="p-name"> Status: ' + Person[index].status + '</div>';
html += '<div class="p-name"> Country: ' + Person[index].country + '</div>';
html += '</div>';
html += '</div>';
任何帮助?

您的代码不完整,但我怀疑您有多个id
infocontainer
<div id="infocontainer">
的元素?
无论如何,这里是如何使用单个var PersonInfo = [{
person_name: "Alice",
image_url: "https://placeimg.com/100/50/people",
status: "alive",
country: "USA"
}, {
person_name: "Bob",
image_url: "https://placeimg.com/100/50/people/sepia",
status: "deceased",
country: "Australia"
}];
PersonInfo.forEach((pi, i) => {
$("#persons div").eq(i).hover(function() {
$i = $("#infocontainer");
$i.find(".p-image img").attr("src", pi.image_url);
$i.find(".p-name span").text(pi.person_name);
$i.find(".p-status span").text(pi.status);
$i.find(".p-country span").text(pi.country);
$i.show();
}, function() {
$("#infocontainer").hide();
});
});
:
#persons div {
display: inline-block;
padding: 2em;
border: 1px solid black;
margin: 1em
}
#infocontainer {
display: none;
position: absolute;
right: 20px;
top: 20px
}
