如何将Tooltip javascript库(qtip.js)与cytoscape.js一起使用 [英] How to use tooltip javascript library(qtip.js) together with cytoscape.js
问题描述
我想使用 qtip 和cytoscape.js一起在鼠标悬停事件中在节点上分发工具提示用cytoscape.js创建的图形.我将以下代码放置在ready:function()中,如下所示:
I want to use qtip together with cytoscape.js to dispaly tooltips in nodes on mouseover event in graph created with cytoscape.js. I have placed following code inside ready: function() as shown below:
cy.on('mouseover','node',function (event) {
var eid = $(this).data('id');
$(this).qtip({
overwrite: false,
content: eid,
position: {
my: 'right center',
at: 'left center',
target: $(this)
},
show: {
event: event.type,
ready: true
},
hide: {
fixed: true
}
}, event);
});
但是,鼠标悬停事件上的节点上没有显示工具提示.请帮助我.
But, there is no tooltip displaying in node on mouseover event.. Please help me.
推荐答案
为qtip提供正确的坐标以与节点悬停进行交互.可以使用cyPosition做到这一点,希望对您有所帮助:
Provide the correct coordinate to qtip to interact with node hovering. It can be done with cyPosition Hope this helps:
cy.on('mousemove','node', function(event){
var target = event.cyTarget;
var sourceName = target.data("source");
var targetName = target.data("target");
var x=event.cyPosition.x;
var y=event.cyPosition.y;
$("#box").qtip({
content: {
title:targetName,
text: sourceName
},
show: {
delay: 0,
event: false,
ready: true,
effect:false
},
position: {
my: 'bottom center',
at: 'top center',
target: [x+3, y+3],
adjust: {
x: 7,
y:7
}
},
hide: {
fixed: true,
event: false,
inactive: 2000
},
style: {
classes: 'ui-tooltip-shadow ui-tooltip-youtube',
tip:
{
corner: true,
width: 24, // resize the caret
height: 24 // resize the caret
}
}
}
});
})
您也没有指定事件目标.并且不要忘了在处理画布时使用mousemove.
also you are not specifying event target. And don't forget to use mousemove while dealing with canvas.
