How can I get the local Storage Value
提问by srinu
var cookieValue = document.getElementById("demo");
var value = cookieValue .getAttribute('value');
if(typeof(Storage)!=="undefined")
{
alert(value);
localStorage.setItem = ("GetData" , value);
alert(localStorage.setItem);
}
function loading()
{
alert("coming");
var allcookies = localStorage.getItem('GetData');
alert(allcookies);
}
Above is the way I am setting localStorage.setItemand I am getting LocalStorage.
But Where I didn't get the output it is showing Null. Please Suggest me any Solution.

Your code should be :
你的代码应该是：
var cookieValue = document.getElementById("demo");
var value = cookieValue .getAttribute('value');
if(typeof(Storage)!=="undefined")
{
alert(value);
localStorage.setItem("GetData" , value);
alert(localStorage.getItem("GetData"));
}
function loading()
{
alert("coming");
var allcookies = localStorage.getItem('GetData');
alert(allcookies);
}
OR
或者
var cookieValue = document.getElementById("demo");
var value = cookieValue .getAttribute('value');
if(typeof(Storage)!=="undefined")
{
alert(value);
localStorage["GetData"] = value;
alert(localStorage["GetData"]);
}
function loading()
{
alert("coming");
var allcookies = localStorage["GetData"];
alert(allcookies);
}

The correct syntax for setItemis
正确的语法setItem是
localStorage.setItem("GetData", value)
localStorage.setItem("GetData", value)
not
不是
localStorage.setItem = ("GetData", value)
localStorage.setItem = ("GetData", value)

Try this
尝试这个
if( window.localStorage ) {
alert(value);
localStorage.setItem("GetData" , value);
}
