javascript - How to redirect on another page and pass parameter in url from table?

Question

How to redirect on another page and pass parameter in url from table ? I've created in tornato template something like this

<table data-role="table" id="my-table" data-mode="reflow">
    <thead>
        <tr>
            <th>Username</th>
            <th>Nation</th>
            <th>Rank</th>
            <th></th>
        </tr>
    </thead>
    <tbody>
        {% for result  in players %}
        <tr>
            <td>{{result['username']}}</td>
            <td>{{result['nation']}}</td>
            <td>{{result['rank']}}</td>
            <td><input type="button" name="theButton" value="Detail"
                       ></td>
        </tr>
    </tbody>
    {% end %}
</table>  

and I would like when I press detail to be redirect on /player_detail?username=username and show all detail about that player. I tried with href="javascript:window.location.replace('./player_info');" inside input tag but don't know how to put result['username'] in. How to do this ?

Answer 1

Set the user name as data-username attribute to the button and also a class:

HTML

<input type="button" name="theButton" value="Detail" class="btn" data-username="{{result['username']}}" />

JS

$(document).on('click', '.btn', function() {

    var name = $(this).data('username');        
    if (name != undefined && name != null) {
        window.location = '/player_detail?username=' + name;
    }
});?

EDIT:

Also, you can simply check for undefined && null using:

$(document).on('click', '.btn', function() {

    var name = $(this).data('username');        
    if (name) {
        window.location = '/player_detail?username=' + name;
    }
});?

As, mentioned in this answer

if (name) {            
}

will evaluate to true if value is not:

• null
• undefined
• NaN
• empty string ("")
• 0
• false

The above list represents all possible falsy values in ECMA/Javascript.
