这次给大家带来树形菜单带复选与级联选择使用详解，树形菜单带复选与级联选择使用的注意事项有哪些，下面就是实战案例，一起来看一下。
具体代码如下所示：
<p id="searchTree"></p>
<script>
var treeData = [{
text: "Parent 1",
nodes: [{
text: "Child 1",
nodes: [{
text: "Grandchild 1"
}, {
text: "Grandchild 2",
nodes: [{
text: "Grandchild 2-1",
nodes: [{
text: "Grandchild 2-1-1"
}, {
text: "Grandchild 2-2-1",
}]
}, {
text: "Grandchild 1-2",
}]
}]
}, {
text: "Child 2",
nodes: [{
text: "Grandchild 2-1"
}, {
text: "Grandchild 2-2",
}]
}]
}, {
text: "Parent 2",
id:'11111'
}, {
text: "Parent 3"
}, {
text: "Parent 4"
}, {
text: "Parent 5"
}];
var nodeCheckedSilent = false;
function nodeChecked(event, node) {
if (nodeCheckedSilent) {
return;
}
nodeCheckedSilent = true;
checkAllParent(node);
checkAllSon(node);
nodeCheckedSilent = false;
}
var nodeUncheckedSilent = false;
function nodeUnchecked(event, node) {
if (nodeUncheckedSilent)
return;
nodeUncheckedSilent = true;
uncheckAllParent(node);
uncheckAllSon(node);
nodeUncheckedSilent = false;
}
//选中全部父节点
function checkAllParent(node) {
$('#searchTree').treeview('checkNode', node.nodeId, {
silent: true
});
var parentNode = $('#searchTree').treeview('getParent', node.nodeId);
if (!("nodeId" in parentNode)) {
return;
} else {
checkAllParent(parentNode);
}
}
//取消全部父节点
function uncheckAllParent(node) {
$('#searchTree').treeview('uncheckNode', node.nodeId, {
silent: true
});
var siblings = $('#searchTree').treeview('getSiblings', node.nodeId);
var parentNode = $('#searchTree').treeview('getParent', node.nodeId);
if (!("nodeId" in parentNode)) {
return;
}
var isAllUnchecked = true; //是否全部没选中
for (var i in siblings) {
if (siblings[i].state.checked) {
isAllUnchecked = false;
break;
}
}
if (isAllUnchecked) {
uncheckAllParent(parentNode);
}
}
//级联选中所有子节点
function checkAllSon(node) {
$('#searchTree').treeview('checkNode', node.nodeId, {
silent: true
});
if (node.nodes != null && node.nodes.length > 0) {
for (var i in node.nodes) {
checkAllSon(node.nodes[i]);
}
}
}
//级联取消所有子节点
function uncheckAllSon(node) {
$('#searchTree').treeview('uncheckNode', node.nodeId, {
silent: true
});
if (node.nodes != null && node.nodes.length > 0) {
for (var i in node.nodes) {
uncheckAllSon(node.nodes[i]);
}
}
}
$('#searchTree').treeview({
showCheckbox: true,
data: treeData,
onNodeChecked: nodeChecked,
onNodeUnchecked: nodeUnchecked
});
</script>
