我一直在使用JointJS一段时间,我正在尝试为我的元素创建一个HTML模板。所以我一直在使用tutorial,但它没有放弃为我做这件事。 我想要完成的是在执行操作时调整HTML元素的颜色,例如双击元素。我确实注意到教程中文本的更改方式,但没有更改任何颜色的示例。
我试过这个来获得元素的起始颜色:
joint.shapes.html = {};
joint.shapes.html.OdinElement = joint.shapes.basic.Rect.extend({
defaults: joint.util.deepSupplement({
type: 'html.Element',
attrs: {
rect: { stroke: 'none', 'fill-opacity': 0 }
}
}, joint.shapes.basic.Rect.prototype.defaults)
});
// Create a custom view for that element that displays an HTML div above it.
// -------------------------------------------------------------------------
joint.shapes.html.OdinElementView = joint.dia.ElementView.extend({
template: [
'<div class="html-element">',
'<button class="delete">x</button>',
'<label></label>',
'<span></span>', '<br/>',
'</div>'
].join(''),
initialize: function() {
_.bindAll(this, 'updateBox');
joint.dia.ElementView.prototype.initialize.apply(this, arguments);
this.$box = $(_.template(this.template)());
this.$box.find('.delete').on('click', _.bind(this.model.remove, this.model));
// Update the box position whenever the underlying model changes.
this.model.on('change', this.updateBox, this);
// Remove the box when the model gets removed from the graph.
this.model.on('remove', this.removeBox, this);
this.updateBox();
},
render: function() {
joint.dia.ElementView.prototype.render.apply(this, arguments);
this.paper.$el.prepend(this.$box);
this.updateBox();
return this;
},
updateBox: function() {
// Set the position and dimension of the box so that it covers the JointJS element.
var bbox = this.model.getBBox();
// Example of updating the HTML with a data stored in the cell model.
this.$box.find('label').text(this.model.get('label'));
this.$box.css({ width: bbox.width, height: bbox.height, left: bbox.x, top: bbox.y, transform: 'rotate(' + (this.model.get('angle') || 0) + 'deg)', background: this.model.get('color')}); // I've tried to add it like a background
},
removeBox: function(evt) {
this.$box.remove();
}
});
//add a new element like this
new joint.shapes.html.OdinElement({
position: { x: 80, y: 80 },
size: { width: 200, height: 50 },
label: 'label',
color: '#ff0000'
});
我也尝试将其设置为标签中设置的文本,但我不知道是否有功能。
有没有人知道如何做到这一点?
非常感谢!

答案 0 :(得分:0)
我自己找到了答案!
显然,不允许在html变量中创建与给定Element不同的元素。所以我必须将joint.shapes.html.OdinElement
更改为joint.shapes.html.Element
,将joint.shapes.html.OdinElementView
更改为joint.shapes.html.ElementView
现在一切正常:)
感谢您的帮助!
