JointJS 模型 - 未分配文本属性

Question

我正在创建一个简单的 joint.shapes.devs.Model 并分配一个文本属性，但文本没有出现，而是标记为 "Model"。

function makeEditableElement(label) {

        var maxLineLength = _.max(label.split('\n'), function(l) { return l.length; }).length;

        // Compute width/height of the rectangle based on the number 
        // of lines in the label and the letter size. 0.6 * letterSize is
        // an approximation of the monospace font letter width.
        var letterSize = 15;
        var width = 2 * (letterSize * (0.3 * maxLineLength + 1));
        var height = 2 * ((label.split('\n').length + 1) * letterSize);

        return new joint.shapes.devs.Model({
            '.label': label,
            size: { width: width, height: height },
            inPorts: [''],
            outPorts: [''],
            attrs: {  '.inPorts circle': { r: 3 ,fill: 'gray', type: 'input',magnet: 'passive'},
                    '.outPorts circle': { r: 3 ,fill: 'gray', type: 'output',magnet:'true' },
                    rect: { width: width, height: height, fill: '#FFF' ,rx: 5,ry: 5, 'stroke-width':1.5,  'stroke': '#555' }, 
                    text: { text: label, fill: '#555' , 'font-size': 13, magnet: true,'font-weight': 'normal'} 
                }
        });
    }  
graph.addCell(makeEditableElement("foo"));
joint.layout.DirectedGraph.layout(graph, { setLinkVertices: false });

如果我遗漏了什么，请指出，因为我是 JointJS 的新手。提前致谢。

Answer 1

'.label' 需要分配一个包含文本属性的对象——您只为其分配字符串 "foo"

请尝试以下操作：

...

'.label': { text: label },

我通过将 attrs 中“.label”的位置更改为以下方式使其工作：

function makeEditableElement(label,x,y) {

        var maxLineLength = _.max(label.split('\n'), function(l) { return l.length; }).length;

        // Compute width/height of the rectangle based on the number 
        // of lines in the label and the letter size. 0.6 * letterSize is
        // an approximation of the monospace font letter width.
        var letterSize = 15;
        var width = 2 * (letterSize * (0.3 * maxLineLength + 1));
        var height = 2 * ((label.split('\n').length + 1) * letterSize);

        return new joint.shapes.devs.Model({
            id: label,
            position: {x:x, y:y},
            size: { width: width, height: height, fill: 'transparent' ,rx: 5,ry: 5, 'stroke-width':1.5,  'stroke': '#31d0c6' },
            inPorts: [''],
            outPorts: [''],
            attrs: {  '.label': {text: label},
                    '.inPorts circle': { r: 3 ,fill: 'gray', type: 'input',magnet: 'passive'},
                    '.outPorts circle': { r: 3 ,fill: 'gray', type: 'output',magnet:'true' },
                    rect: { width: width, height: height, fill: 'transparent' ,rx: 5,ry: 5, 'stroke-width':1.5,  'stroke': '#31d0c6' },
                    text: { text: label, magnet: true, 'font-size': letterSize, 'font-family': 'monospace' }
                }
        });
    }
