刪除陣列使用JavaScript

Question

存儲在本地存儲這是我的多維數組：

[ 
    {"leads":"Akhil","email":"anand@patel.com","phone":"9999-999-999","referance":"ByReferance","nameref":"Anand","preftime":"Afteroon"}, 
    {"leads":"Anand","email":"a@a.com","phone":"9998789333","referance":"email","nameref":"AAA","preftime":"Afteroon"} 
] 

我想刪除從多維數組這個數組，按鈕

{"leads":"Akhil","email":"anand@patel.com","phone":"9999-999-999","referance":"ByReferance","nameref":"Anand","preftime":"Afteroon"}

的OnClick事件

，怎麼可能？

Answer 1

想這是從localstorage.getItem("contacts");

var value = JSON.parse(localstorage.getItem("contacts")); 

這個例子

var value = [{"leads":"Akhil","email":"anand@patel.com","phone":"9999-999-999","referance":"ByReferance","nameref":"Anand","preftime":"Afteroon"},{"leads":"Anand","email":"a@a.com","phone":"9998789333","referance":"email","nameref":"AAA","preftime":"Afteroon"}]; 

起見，假設你要刪除基於該leads name一個項目中獲得的價值，你需要循環，並找到出所需索引

var index = -1; 
for (var counter = 0; counter < value.length; counter++) 
{ 
    if (value[ counter ].leads == "Akhil") 
    { 
     index = counter; 
     break; 
    } 
} 

所有你需要的做的是從值陣列

value.splice(0,1); // index = 1 

除去第一項目和設定值回localStorage的

localstorage.setItem("contacts", JSON.stringify(value));
