使用剪接功能删除。方法Array.splice（索引，1）; –

你想根据名称找出数组中的项目吗？ – gurvinder372

想这是从localstorage.getItem("contacts");

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

这个例子

var value = [{"leads":"Akhil","email":"[email protected]","phone":"9999-999-999","referance":"ByReferance","nameref":"Anand","preftime":"Afteroon"},{"leads":"Anand","email":"[email protected]","phone":"9998789333","referance":"email","nameref":"AAA","preftime":"Afteroon"}];

起见，假设你要删除基于该leads name一个项目中获得的价值，你需要循环，并找到出所需索引

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从值阵列

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

除去第一项目和设定值回localStorage的

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

OP可能需要一个_loop_才能找到目标元素。 – Rayon
