我有一个使用 jQuery 的展开/折叠，它在第一层工作得很好:
这是我的 Razor 文件:
@model IntDashMakeRecAssgnmntsPoRespMngrVM
<div style="border:1px dotted blue;padding:5px">
<div>
<i class="fa fa-user-circle"></i> <i class="fa fa-user-circle"></i>
</div>
<i id="collapseMakeRecAssignments" title="Show Make Recommendation Assignments" class="fa fa-plus-circle pull-left" style="display:block;cursor:pointer"></i>
<i id="expandMakeRecAssignments" title="Hide Make Recommendation Assignments" class="fa fa-minus-circle pull-left" style="display:none;cursor:pointer"></i>
<span style="margin-left:2px">Make Recommendation Assignment for POs and Responsible Manager (@Model.Audits.Count())</span>
<div id="MakeRecommendationAssignmentsDiv" style="display:none;margin-left:40px;padding:5px;border:0px dotted black">
@foreach (var audit in Model.Audits)
{
<div>
<i id="expandRecommendations@(audit.AuditID)" title="Show Recommendations Needing Assignment" class="fa fa-plus-circle pull-left" style="display:block;cursor:pointer"></i>
<i id="collapseRecommendations@(audit.AuditID)" title="Hide Recommendations Needing Assignment" class="fa fa-minus-circle pull-left" style="display:none;cursor:pointer"></i>
<span style="margin-left:2px"><b>@audit.AuditAcnCd</b></span>
<div id="RecommendationDiv@(audit.AuditID)" style="margin-left:40px;padding:5px;border:0px dotted black">
@foreach(var finding in audit.Findings)
{
foreach(var rec in finding.Recommendations)
{
<div style="display:none;">
<a asp-controller="InternalRecommendations" asp-action="Details" asp-route-id="@rec.RecommendationId"
title="Make assignment for @audit.AuditAcnCd">
<b>@audit.AuditAcnCd/@finding.FindingCd/@rec.RecCd</b>
</a>
</div>
}
}
</div>
</div>
}
</div>
</div>
这是我的 jQuery:
$("#collapseMakeRecAssignments, #expandMakeRecAssignments").click(function () {
$("#MakeRecommendationAssignmentsDiv").toggle();
$("#collapseMakeRecAssignments, #expandMakeRecAssignments").toggle();
});
让第一层展开和折叠非常简单。
但现在我需要在展开的 div 中嵌套 3 个新显示的 div 来进行每次展开。
这是我正在编写的 jQuery，用于尝试扩展内部 div。
// Wire up dynamic toggle
var expandNodes = $('i[id^="expandRecommendations"]');
expandNodes.each(function (index) {
console.log(this.id);
console.log(parseInt(this.id.replace(/[^0-9\.]/g, ''), 10));
expandNodeId = parseInt(this.id.replace(/[^0-9\.]/g, ''), 10);
expandNodeDivId = "RecommendationDiv" + expandNodeId;
console.log("#" + expandNodeDivId)
$("#" + expandNodeDivId).click(function (e) {
$("#" + expandNodeDivId).toggle();
});
});
在这一行中: var ExpandNodes = $('i[id^="expandRecommendations"]'); 我得到的所有 i 标签都有一个 font Awesome 类(+ 圆圈符号)作为展开按钮。
现在，我滚动浏览 ExpandNodes 集合中的每个“+ 圆圈”按钮，并获取我使用服务器端构建的 razor 分配给每个按钮的唯一 ID(
<div id="RecommendationDiv@(audit.AuditID)" style="display:none;margin-left:40px;padding:5px;border:0px dotted black">
并尝试为每个元素添加一个点击事件来切换自身，该事件应该显示自身以及嵌套在自身内部的 anchor div:
但它不会扩展。
以下是 console.logs，显示我获得了正确的 id 来调用要展开的元素:
这些 console.log 行显示我正在获取写入信息以尝试连接它，但我无法让它们扩展:
expandRecommendations279938 // the div I clicked on
279938 // able to parse the audit id from the id of the element I clicked on.
#RecommendationDiv279938 // concatenated the Text part of the element I want to expand with the id for the second part of the element to expands id.
有人看到这里的问题了吗？任何帮助将不胜感激。

最佳答案
我明白了。
这是修改后的 JavaScript:
// Wire up dynamic toggle
var expandNodes = $('i[id^="expandRecommendations"]');
expandNodes.each(function (index) {
expandNodeId = parseInt(this.id.replace(/[^0-9\.]/g, ''), 10);
create_expand_toggle(expandNodeId);
});
function create_expand_toggle(nodeId) {
$("#" + "expandRecommendations" + nodeId).click(function (e) {
console.log("Clicking");
$("#" + "RecommendationDiv" + nodeId).toggle();
});
}
我引用了我想在按钮单击中展开的同一个 div。我需要对 i 标签进行第二次引用，其中字体 Awesome + class 充当连接单击事件的按钮。
一次小费。我尝试为两个节点 id 引用创建一个 var 并使用它们，这样它会更具可读性。但是该级别上所有三个加号的单击事件都显示相同的 div。最后一个分区。所以我必须在 create_expand_toggle 函数中连接 ids。
