[英]remove all child elements from google org chart
i'm using google organization chart to build chart similar to the attached screenshot. 我正在使用谷歌组织结构图来构建类似于附加屏幕截图的图表。
there is a method called removeRow(nodeIndex) that is used to remove a node from chart, but the problem is that this method only remove the node, without removing the child elements of the node. 有一个名为removeRow(nodeIndex)的方法,用于从图表中删除节点,但问题是此方法仅删除节点,而不删除节点的子元素。
so, for example when the user selects 3 and click remove i want to create a function that remove (3,7,8,9,10) and not only 3. 所以,例如当用户选择3并单击删除时,我想创建一个删除(3,7,8,9,10)而不仅仅是3的函数。
i try to create this function and this is my code: 我尝试创建此功能,这是我的代码:
<script type='text/javascript'>var counter; var childs1= new Array();</script>
<script>
$('#remove').click(function(){
// this method return all childs indexes for the selected node(7,10)
childs1=chart.getChildrenIndexes(selected_node);
counter=childs1.length;
for(var i=0;i< counter;i++)
{
getChilds(childs1[i]);
}
for(var i=0;i< childs1.length;i++)
{
data.removeRow(childs1[i]);
}
})
}
function getChilds(child)
{
var childs2=new Array();
childs2=chart.getChildrenIndexes(child);
childs1.concat(childs2);
counter+=childs2.length;
}
but nothing happend. 但没有任何事情发生。 my question is: how can i create a function that returns array of all selected node children, and the chilren of each child (in this example the returned array :(3,7,8,9,10))? 我的问题是:我如何创建一个函数来返回所有选定节点子节点的数组,以及每个子节点的chilren(在这个例子中返回的数组:(3,7,8,9,10))?
Thank You 谢谢
代码中的问题是我忘了在concat之后引用childs1:
childs1=childs1.concat(childs2);
