如何在单击其他元素时显示元素？

Question

I have a link,

<a href="manager_view.html">
    <p class="in_row">Jane Doe</p>
</a>

I want to show a checkmark, ✓, when Jane Doe has been clicked in the past. How would I do that?

Answer 1

FIDDLE

JAVASCRIPT

document.getElementsByClassName('in_row')[0].onclick = function()
{
    this.className = 'in_row clicked';
}

Or, if you have more than one:

var rows = document.getElementsByClassName('in_row');
for (var i = 0, len = rows.length; i < len; i++)
{
    rows[i].onclick = doclick; //this function is the above code
}

CSS

.clicked:before
{
    content:"✓";
}

Answer 2

You should use local storage http://www.w3schools.com/html/html5_webstorage.asp If you have more elements to store in it you can use JSON.stringify When you create a array of clicked elements you store it like this

  localStorage["rowsclick"] = JSON.stringify(elementsClickedArray);

And than to read that you need

 elementsClickedArray = JSON.parse(localStorage["rowsclick"]);
