Vue.js中如何使checked数组与symptoms数组长度一致

"const symptoms = reactive({});\n\nconst checked = reactive({});\n\nasync function onVisibleChange(visible) {\n if (visible) {\n const symptom = await defHttp.get({ url: '/checkItemDetail/checkItemDetail/getSymptom' });\n Object.assign(symptoms, symptom);\n checked.value = Array(symptoms.value.length).fill(false);\n }\n}\n\n"\n\n这样，checked就会成为一个与symptoms长度一致的数组，并且每个元素的初始值都为false。
