我实现了一个小GrapesJS编辑器,该编辑器允许编辑Django / Jinja2模板。默认情况下,GrapesJS试图获取我元素的图像src
:
<a href="{{product_url}}" target="_blank"><img src="{{image_url}}" width="130"/></a>
每次我将HTML模板加载到GrapesJS编辑器中时,都会发生请求:
http://localhost:8000/%7B%7Bimage_url%7D%7D 404 (Not Found)
即使此404调用,GrapesJS编辑器也可以正常工作。但是我想处理对图像的请求。因此,我不想渲染GrapesJS的http://localhost:8000/%7B%7Bimage_url%7D%7D
默认调用,而是渲染一个占位符图像:https://placekitten.com/200/300
我目前拥有的东西:
editor = grapesjs.init({
container: '#gjs',
assetManager: {},
});
editor.setComponents('<a href="{{product_url}}" target="_blank"><img src="{{image_url}}" width="130"/></a>');
// querySelector is returning an empty Array of Nodes
editor.on('load', () => {
const body = editor.Canvas.getBody().ownerDocument;
body.querySelectorAll('a').forEach(function(el) {
let link = el;
link.setAttribute('src', "http://via.placeholder.com/350x150");
});
editor.store();
});
