const formElementTemplate = document.querySelector('.my-form-element-template');
// use DOM api
const nodeA = document.createElement('msc-ai-prompt');
document.body.appendChild(nodeA);
nodeA.appendChild(formElementTemplate.content.cloneNode(true));
nodeA.config = {
systemPrompt: '',
temperature: .8,
topK: 3
};
nodeA.disabed = false;
// new instance with Class
const nodeB = new MscAiPrompt();
document.body.appendChild(nodeB);
nodeB.appendChild(formElementTemplate.content.cloneNode(true));
nodeB.config = {
systemPrompt: '',
temperature: .8,
topK: 3
};
nodeB.disabed = true;
// new instance with Class & default config
const config = {
config: {
systemPrompt: '',
temperature: .8,
topK: 3
}
};
const nodeC = new MscAiPrompt(config);
document.body.appendChild(nodeC);
nodeC.appendChild(formElementTemplate.content.cloneNode(true));
