您好，我已在图表中添加了一些功能，可在单击该点时克隆该工具提示，并将其显示在屏幕上，直到再次单击该点将其关闭为止。
现在我要做的是，当我将鼠标悬停在已单击的点上时，我不希望从悬停中显示另一个工具提示。基本上，它会创建一个重复项，但我不希望它在已有克隆的工具提示时显示另一个工具提示。
这是我创建的图表的代码：
def Spline(self,crv,ren,iren):
extract = vtk.vtkExtractVOI()
puntosVTK=dental_curve.puntos_vtk(crv)
spline = vtk.vtkSplineWidget()
spline.InitializeHandles(puntosVTK) #insertamos los puntos
spline.SetCurrentRenderer(ren)
spline.SetDefaultRenderer(ren)
spline.SetInputConnection(extract.GetOutputPort())
spline.SetInteractor(iren)
spline.ProjectToPlaneOn()
spline.SetProjectionNormalToXAxes()
spline.On()
return spline
这是我目前关注的代码：
<dependency>
<groupId>org.messaginghub</groupId>
<artifactId>pooled-jms</artifactId>
</dependency>
如您所见，我在单击时克隆了工具提示，还有一个/***************************************************************

事件，如果已有重复，我试图隐藏该工具提示。
以下代码正在运行，正在检查是否存在克隆，并且此部分正常运行。我现在要做的就是隐藏工具提示
point: {
events: {
mouseOver: function (event) {
console.log(event.target.category);
if (jQuery.inArray(event.target.category, chart_1_1_checkx) != -1) {
}
},
click: function (event) {
//check if point was already clicked
var x = chart_1_1_checkx.indexOf(event.point.x);
if ( x >= 0 ) {
//remove tooltip
$(chart_1_1_cloneFrame[x]).remove();
$(chart_1_1_cloneText[x]).remove();
//remove x coordinate and clone from array --> tooltip can be displayed again
chart_1_1_cloneText.splice(x, 1);
chart_1_1_cloneFrame.splice(x, 1);
chart_1_1_checkx.splice(x, 1);
} else {
var chart_1_1_cloneDiv = this.series.chart.tooltip.label.div.cloneNode(true),
chart_1_1_cloneToolTip = this.series.chart.tooltip.label.element.cloneNode(true);
chart_1_1.container.appendChild(chart_1_1_cloneDiv);
chart_1_1.container.firstChild.appendChild(chart_1_1_cloneToolTip);
//save coordinates and tooltip object
chart_1_1_checkx.push(event.point.x);
chart_1_1_cloneFrame.push(chart_1_1_cloneToolTip);
chart_1_1_cloneText.push(chart_1_1_cloneDiv);
}
}
}
}
我所需要的只是我在问题中指定的if语句中的一行代码，当我将鼠标悬停在该提示上时，它会隐藏该提示。 if语句基本上是在说“这里已经有一个克隆的工具提示，所以当我将鼠标悬停在上面时，不要打扰显示另一个”。
我尝试了以下方法，但均无效：
mouseOver以及更多内容，如果您有任何想法，请分享。我想它会是一个非常简单的班轮，但我只是想不通。预先感谢！
答案 0 :(得分：1)
您只需在this.series.chart.tooltip.label上隐藏mouseOver并在mouseOut上显示它即可。
代码：
point: {
events: {
mouseOver: function(event) {
if (jQuery.inArray(event.target.category, chart_1_1_checkx) !== -1) {
this.series.chart.tooltip.label.hide();
}
},
mouseOut: function(event) {
if (jQuery.inArray(event.target.category, chart_1_1_checkx) === -1) {
this.series.chart.tooltip.label.show();
}
}
}
}
