Hello! In localStorage you can store strings only. If you need to store array or object you can save them as JSON string and parse when you retrieve it.
For example to save array prelocalStorage.setItem("arrayName", JSON.stringify(data));/prewhere data - variable which contains array with data. To read prevar arrayFromLS;
try {
arrayFromLS = JSON.parse(localStorage.getItem("arrayName"));
if ({}.toString.call(arrayFromLS) !== "[object Array]") {
arrayFromLS = [];
}
} catch ( e ) {
arrayFromLS = [];
}/pre
It's working Maryna..thnk u
now i want to compare with input box value from array value .how to do it???
var arr = JSON.parse(localStorage.getItem("cityarray"));
try {
if ({}.toString.call(arr) !== "[object Array]")
{
var x = document.getElementsByName("inputcity").value;
alert(x);
}
else
{
alert(arr[0]['male']);
}
} catch ( e ) {
alert("Parse Error. Some wierd data in localstorage...");
}
It's not working....
Hi Pritu,
What exactly doesn't work? What alert is displayed?
actually I want to
first store array value in localsotrage as above Maryna told me and i got that solution
second I have input box and in that i enter city name i want to retrive it and check with arrary value that i store in local storage..
for example {mumbai,pune,delhi} is my array
for example input box have pune
then the condition will true and city will find and call another service.
if condition flase then i want to open popup dialog and choose city from that and call service.
it's possible??
Hello!
1) prevar arr = JSON.parse(localStorage.getItem("cityarray")); /pre should be inside try..catch
2) Instead predocument.getElementsByName("inputcity").value/pre use preAppery("componentName").val()/pre3) pre {mumbai,pune,delhi}/pre is not json array. Array should look like this pre["mumbai","pune","delhi"]/pre4) To check if there is x value in arr array use preif (arr.indexOf(x) !== -1) {
//we have this value in array
} else {
//there is no such value in array
}/pre
thnks Maryna...It's working..
but i tried follow code.
var arr = JSON.parse(localStorage.getItem("CityArray"));
try {
if (arr)
{
Code: Select all
var city=localStorage.getItem("c");
if (arr.indexOf(city) !== -1)
{ alert(true);
}
else
{
alert(false);
}
Code: Select all
} else
{
alert("array null");
}
} catch ( e ) {
alert(e);
}
