英文:
How can I remove all objects which are having `areWeCreatingNewUser` property
问题
const obj = {"title": "sample","status": 0,"creationDate": null,"userGroup": "","signatureDelay": "2023-06-05T11:07:18.786Z","listSign": [],"priority": false,"nature": null,"qesData": {"signatories": [{"displayName": "Some user","email": "someuser@hotmail.com","firstname": "User first name","id": "4ffb81f6-6efd-4e41-9168-b032ab3e3b04","lastname": "User last name","locale": "en","signatoryAttributes": []},{"email": "test@hotmail.com","displayName": "","areWeCreatingNewUser": true},{"email": "test1@hotmail.com","displayName": "","areWeCreatingNewUser": true}]},"fileName": "sample.pdf",};for (var i = obj.qesData.signatories.length - 1; i >= 0; i--) {if (obj.qesData.signatories[i].areWeCreatingNewUser) {obj.qesData.signatories.splice(i, 1);}}
这段代码会遍历 qesData => signatories 数组，并删除其中所有具有 areWeCreatingNewUser 属性设置为 true 的对象。这里使用了一个反向遍历的方式，从数组的末尾开始，以避免修改数组时导致索引错位的问题。
英文:
I have the following object
const obj = {"title": "sample","status": 0,"creationDate": null,"userGroup": "","signatureDelay": "2023-06-05T11:07:18.786Z","listSign": [],"priority": false,"nature": null,"qesData": {"signatories": [{"displayName": "Some user","email": "someuser@hotmail.com","firstname": "User first name","id": "4ffb81f6-6efd-4e41-9168-b032ab3e3b04","lastname": "User last name","locale": "en","signatoryAttributes": []},{"email": "test@hotmail.com","displayName": "","areWeCreatingNewUser": true},{"email": "test1@hotmail.com","displayName": "","areWeCreatingNewUser": true}]},"fileName": "sample.pdf",}
I need to loop through the qesData => signatories array and remove all of the objects there which are having areWeCreatingNewUser property set to true.
So I tried
for(var i = 0;i < obj.qesData.signatories.length;i++) {if(obj.qesData.signatories[i].areWeCreatingNewUser) {obj.qesData.signatories.splice(i,1);}}
the problem here is that the first time when it founds the user with email test@hotmail.com it remove it with splice at index 1 and after that the obj.qesData.signatories is modified and on next iteration it does not remove the user with email test1@hotmail.com
How can I solve this issue ?
Also I forgot to mention that I need to use old javascript code,filter is not an option

你可以使用一个过滤器，只保留 areWeCreatingNewUser 不是 true 的对象。
obj.qesData.signatories = obj.qesData.signatories.filter(signatory => signatory.areWeCreatingNewUser !== true);
英文:
You can use a filter to only have objects where areWeCreatingNewUser is not true
obj.qesData.signatories = obj.qesData.signatories.filter(signatory =>signatory.areWeCreatingNewUser !== true);

你可以使用Array.filter()来实现它。
const obj = {"title": "sample","status": 0,"creationDate": null,"userGroup": "","signatureDelay": "2023-06-05T11:07:18.786Z","listSign": [],"priority": false,"nature": null,"quesData": {"signatories": [{"displayName": "Some user","email": "someuser@hotmail.com","firstname": "User first name","id": "4ffb81f6-6efd-4e41-9168-b032ab3e3b04","lastname": "User last name","locale": "en","signatoryAttributes": []},{"email": "test@hotmail.com","displayName": "","areWeCreatingNewUser": true},{"email": "test1@hotmail.com","displayName": "","areWeCreatingNewUser": true}]},"fileName": "sample.pdf",}obj.qesData.signatories = obj.qesData.signatories.filter(d => !d.areWeCreatingNewUser)console.log(obj)
更新：对于 ES5 风格，以下是参考代码：
const obj = {"title": "sample","status": 0,"creationDate": null,"userGroup": "","signatureDelay": "2023-06-05T11:07:18.786Z","listSign": [],"priority": false,"nature": null,"quesData": {"signatories": [{"displayName": "Some user","email": "someuser@hotmail.com","firstname": "User first name","id": "4ffb81f6-6efd-4e41-9168-b032ab3e3b04","lastname": "User last name","locale": "en","signatoryAttributes": []},{"email": "test@hotmail.com","displayName": "","areWeCreatingNewUser": true},{"email": "test1@hotmail.com","displayName": "","areWeCreatingNewUser": true}]},"fileName": "sample.pdf",}let data = []for (let d of obj.qesData.signatories) {if (!d.areWeCreatingNewUser) {data.push(d)}}obj.qesData.signatories = dataconsole.log(obj)
英文:
You can use Array.filter() to do it
<!-- begin snippet: js hide: false console: true babel: false -->
<!-- language: lang-js -->
const obj = {"title": "sample","status": 0,"creationDate": null,"userGroup": "","signatureDelay": "2023-06-05T11:07:18.786Z","listSign": [],"priority": false,"nature": null,"qesData": {"signatories": [{"displayName": "Some user","email": "someuser@hotmail.com","firstname": "User first name","id": "4ffb81f6-6efd-4e41-9168-b032ab3e3b04","lastname": "User last name","locale": "en","signatoryAttributes": []},{"email": "test@hotmail.com","displayName": "","areWeCreatingNewUser": true},{"email": "test1@hotmail.com","displayName": "","areWeCreatingNewUser": true}]},"fileName": "sample.pdf",}obj.qesData.signatories = obj.qesData.signatories.filter(d => !d.areWeCreatingNewUser)console.log(obj)
<!-- end snippet -->
Update: for ES5 style,below is a reference for you
<!-- begin snippet: js hide: false console: true babel: false -->
<!-- language: lang-js -->
const obj = {"title": "sample","status": 0,"creationDate": null,"userGroup": "","signatureDelay": "2023-06-05T11:07:18.786Z","listSign": [],"priority": false,"nature": null,"qesData": {"signatories": [{"displayName": "Some user","email": "someuser@hotmail.com","firstname": "User first name","id": "4ffb81f6-6efd-4e41-9168-b032ab3e3b04","lastname": "User last name","locale": "en","signatoryAttributes": []},{"email": "test@hotmail.com","displayName": "","areWeCreatingNewUser": true},{"email": "test1@hotmail.com","displayName": "","areWeCreatingNewUser": true}]},"fileName": "sample.pdf",}let data = []for(d of obj.qesData.signatories){if(!d.areWeCreatingNewUser){data.push(d)}}obj.qesData.signatories = dataconsole.log(obj)

你可以使用filter()方法。
const obj = {"title": "sample","status": 0,"creationDate": null,"userGroup": "","signatureDelay": "2023-06-05T11:07:18.786Z","listSign": [],"priority": false,"nature": null,"qesData": {"signatories": [{"displayName": "Some user","email": "someuser@hotmail.com","firstname": "User first name","id": "4ffb81f6-6efd-4e41-9168-b032ab3e3b04","lastname": "User last name","locale": "en","signatoryAttributes": []},{"email": "test@hotmail.com","displayName": "","areWeCreatingNewUser": true},{"email": "test1@hotmail.com","displayName": "","areWeCreatingNewUser": true}]},"fileName": "sample.pdf",}obj.qesData.signatories = obj.qesData.signatories.filter(item => !item.areWeCreatingNewUser);console.log(obj)
