I wanted to ask why innerHTML is not working in the following code:

document.getElementById('text').innerHTML = localStorage["mytext"];

The element with the id text is a div element. localStorage is giving me the right String if I use it with alert, what could the error be?

回答1:

Make sure the div exists before trying to reference it,

window.addEventListener("load",function() {
    document.getElementById('text').innerHTML = localStorage.getItem("mytext");
},false);

That will wait for the document to load before doing any modifications

回答2:

Can you check if the localStorage["text"] really returns a string? Maybe this link might help you to check the if it's really a string.
