js删除数组中某个特定的对象

var result.list = [{"key":"预约 ","value":"预约  "},{"key":"现场结束 ","value":"现场结束"},{"key":" 转运维","value":"转运维 "},{"key":" ","value":" "}]

//如果要删除对象包含key="现场结束"的对象则

result.list.push({"key":"预约","value":"预约"});

var li = result.list;
var index;
if('${fwob.ordersource}'== '本地自建'){
for(var i=0;i<li.length;i++){
    if((li[i].key).indexOf("现场结束")>-1){
index = i;
li.splice(index,1);
}
}

}
