Pass JavaScript Object Data into Bootstrap Modal

Question

I've looped through each object and passed each object's data to it's own div along with a button, in each div, that opens a modal window when clicked and displays the data for only that particular object.

However, my problem is, when i test each button to see if it's data displays I would see that the last object's data is displayed for all of the objects modal window. any ideas?

The difference between an ID and a class is that an ID can be used to identify one element, whereas a class can be used to identify more than one.

So you should change id with class

Here is your code :

<button type='button' id='button' data-toggle='modal' data-target='#myModal'>" + "Click me!" + "</button>

Here is modified code:

<button type='button' class='button' data-toggle='modal' data-target='#myModal'>" + "Click me!" + "</button>

Also you have loop where you are trying to attach event on #button click which attach several event on #button and when you click on button it fire many time so if you want to avoid this many time fire you should attach event outside from loop.

for (i = 0; i < radio.length; i++){
    var qb = radio[i].name;
    document.getElementById('box').innerHTML += "<div class='box2'>" + radio[i].name + "<br>" + radio[i].address + "<br> <button type='button' id='button' data-toggle='modal' data-target='#myModal'>" + "Click me!" + "</button></div>";
}

$(document).ready(function(){
   $("#button").click(function(){
       $("#main-content").html(qb);
   });
});

Also if you want to show radio.name in content when click button you should use data- attribute it is my advice. change your code with this:

for (i = 0; i < radio.length; i++){
    var qb = radio[i].name;
    document.getElementById('box').innerHTML += "<div class='box2'>" + radio[i].name + "<br>" + radio[i].address + "<br> <button type='button' class='button' data-toggle='modal' data-target='#myModal' data-radio-name='" + qb + "'>" + "Click me!" + "</button></div>";
}

$(document).ready(function(){
   $(".button").click(function(){
       $("#main-content").html($(this).data('radio-name'));
   });
});

Store arbitrary data associated with the matched elements or return the value at the named data store for the first element in the set of matched elements.

try using event delegation and use .on('click',function) rather than .click(function)

BERRY Over a year ago

if i wanted to pass html along with the object data, so to give the data some structure, how would one go about that?

You should put JSON.stringify(objectData) in data- attribute and if you want to get this object you should use JSON.parse($(this).data('something'))
