javascript - How to pass data from one page to another page html

Question

I have a page1.html which contains set of data

{'key1':'value1','key2':'value2','key3':'value3'}

and a link

<a target='_blank' href='page2.html'>Click To Navigate</a>

which will navigate to page2.html.

I would like to ask how can I pass all the data above in page1.html to page2.html so that I can use them in page2.html.

What I tried to use is localStorage, but I can store only 1 set of data at a time, so if in my page1.html have many set of data, same key but different value they will be overlapped when I store them in localStorage, then I can not pass all these set of data to the page2.html.

Anyone got an idea? Thank you so much

You can do it using Javascript, there's no restriction of which kind of object you can pass. For instance, if you have several key-value objects:

var firstData = {
    'key1' : 'value1',
    'key2' : 'value2'
};

and

var secondData = {
    'key1' : 'value3',
    'key2' : 'value4'
};

you could enclose them using a Javascript array:

// This is on page1.html
var myData = [ firstData, secondData ];

and pass that array using localStorage.

Javascript on page1.html

// Set the variable
localStorage.setItem( 'objectToPass', myData );

Javascript on page2.html

// Get the variable
var myData = localStorage['objectToPass'];
localStorage.removeItem( 'objectToPass' ); // Clear the localStorage
var firstData = myData[0];
var secondData = myData[1];
alert('firstData: ' + firstData + '
secondData: ' + secondData);
