错误：无效值为属性width =“ - Infinity”jsPlumb

Question

我有一个函数可以在两个divs之间创建一个以模态显示的行。错误：无效值为<svg>属性width =“ - Infinity”jsPlumb

//A function that creates line instance. 
function myid_create_line_instance(){ 

    jsPlumb_instance[0] = jsPlumb.getInstance();    
    var id1 = 'tpl_preview_line_1_pair_1'; 
    var id2 = 'tpl_preview_line_1_pair_2'; 


    var endpointOptions = { 
     anchor:'BottomCenter', 
     maxConnections:1,      
     endpoint:['Rectangle',{width:'1px', height:'1px' }], 
     paintStyle:{fillStyle:'#00000', dashstyle:'3 3'}, 
     connectorStyle:{lineWidth:'1px',strokeStyle:'#000000'}, 
     connector:['Straight'],           
    }; 

    div1Endpoint = jsPlumb_instance[0].addEndpoint(id1, endpointOptions); 
    div2Endpoint = jsPlumb_instance[0].addEndpoint(id2, endpointOptions);  

    jsPlumb_instance[0].connect({ 
     source:div1Endpoint, 
     target:div2Endpoint, 
    }); 
    jsPlumb_instance[0].draggable(id1); 
    jsPlumb_instance[0].draggable(id2); 
} 

执行代码后，将其抛出2错误：

Error: Invalid value for <svg> attribute width="-Infinity" jsPlumb-

我尝试的下面jsPlumb初始化后右代码的第一行;然后连接两个div后，下面的第二行代码，没有运气。

jsPlumb_instance[0].setSuspendDrawing(true); 
jsPlumb_instance[0].setSuspendDrawing(false, true); 

我甚至尝试了批处理方法，但没有什么改变。

jsPlumb_instance[0].batch(function() { 
//Codes about connecting the two points of line. 
}, false); 

我注意到的一件事是应该连接我的模态中的两个点的线没有在模态中找到。请参见下面的图片：

我也尝试下面的代码，但仍时有发生的问题。

jsPlumb_instance[id].repaintEverything();

我遇到了同样的错误，当我的容器没有任何大小。我可以假设你应该为jsPlumb实例明确指定容器：

jsPlumb.getInstance({ Container:"editor" });
