最好使用lodash,我如何比较两个对象,如果任何属性匹配,则返回false,而排除'name'。
array1 = [
{
"name": "componentA",
"img": "www.url.com/image1.jpg"
},
{
"name": "componentB",
"header": "this is the default header",
"text": "here is a default text post",
"buttons": [{
"title": "a button",
"url": "http://www.url.com"
}]
},
{
"name": "componentB",
"header": "this is the default header 2",
"text": "here is a default text post 2 ",
"buttons": [
{
"title": "a button 2",
"url": "http://www.url2.com"
},
{
"title": "a second button 2",
"url": "http://www.url2_1.com"
}
]
}
]
vs
array2 = [
{
"name": "componentA",
"img": "www.url.com/imageA.jpg"
},
{
"name": "componentB",
"header": "header changed",
"text": "text post changed",
"buttons": [{
"title": "button changed",
"url": "http://www.website.com"
}]
},
{
"name": "componentB",
"header": "header 2 changed",
"text": "here is a default text post 2 ",
"buttons": [
{
"title": "button 2 changed",
"url": "http://www.website2.com"
},
{
"title": "button 2 changed again",
"url": "http://www.website2_1.com"
}
]
},
]
您可以看到除了array2[2].text
中的每个属性都发生了变化,这将导致错误。
目标是比较两个数组,并确保最终数组中都不存在默认占位符文本。如果存在任何默认的占位符文本,则不允许提交表格。每个对象都有一个name
密钥,需要从检查中排除,因为它是呈现组件的原因。
首先使用_.isequal((,但不确定如何检查两者之间的每个属性。
let results = _.isEqual(array1, array2)
您可以使用_.isEqualWith
和customizer
