从数据库动态添加可嵌套 div 内容后遇到问题。
可嵌套的静态数据按预期工作。我可以从 nestable2 添加项目并查看序列化输出中的更改。
具有动态数据的可嵌套 失去了从可嵌套2到可嵌套的拖放功能,尽管在可嵌套中拖放似乎仍然有效。但是,更改不会反映在序列化输出中。
此外,用于可嵌套的序列化输出的动态数据版本似乎不完整。比较两个链接之间的可嵌套序列化输出表明,可嵌套动态数据链接的 JSON 对象在 Metal 类别菜单之后结束,尽管完整菜单显示在该页面上的可嵌套 div 和 tshoot innerHTML 中。
谁能指出我正确的方向来解决这个问题?
谢谢!
问题太模糊?好的,让我添加更多细节。
下面是一些从 JSON 构建可嵌套菜单的代码:
...函数构建项目(项目){
var html = "<li class='dd-item' data-id='" + item.id + "' id='" + item.id + "'>";
html += "<div class='dd-handle'>" + item.id + "</div>";
if (item.children) {
html += "<ol class='dd-list'>";
$.each(item.children, function (index, sub) {
html += buildItem(sub);
});
html += "</ol>";
}
html += "</li>";
return html;
}
$.each(JSON.parse(obj), function (index, item) {
$('#nestable2 ul').append(buildItem(item));
}); ...
我将硬编码版本中的列表与动态版本进行了比较,发现好的硬编码版本以 ol 标记开头,而动态版本以 ul 标记开头(由于某种原因无法在本文中提供 html)。所以我将代码更改为
...
功能构建项目(项目){
var html = "<li class='dd-item' data-id='" + item.id + "'>";
html += "<div class='dd-handle'>" + item.id + "</div>";
if (item.children) {
html += "<ol class='dd-list'>";
$.each(item.children, function (index, sub) {
html += buildItem(sub);
});
html += "</ol>";
}
html += "</li>";
return html;
}
$.each(JSON.parse(obj), function (index, item) {
$('#nestable2 ol').append(buildItem(item));
}); ...
并使 nestable2 div 以 ol 标记开头。
那种工作,但现在我得到了额外的孩子(例如,塑料,阀门,加热和冷却,库存夹具和杂项附加到金属。阀门,加热和冷却,库存夹具和杂项附加到塑料和库存夹具和杂项附加到加热和冷却。
很明显 if (item.children) 循环存在问题。
有没有人看到这个问题,也许是一个建议的修复?
这是有效的 JSON:

在新的序列化输出中看到的 JSON 具有: ... {"id":"1/2 ST 45"},{"id":"Plastic","children":[{"id":"Pipe" 。 .. 而有效的 JSON 具有: ... {"id":"1/2 ST 45"}]},{"id":"Tees","children":[{"id":"1/2 x 1/2 x 3/4"} ..
请注意,新的序列化输出在 {"id":"1/2 ST 45"} 之后缺少 ']}'
TIA。
