Question

I'm having a problem with my java script. The Modal works fine at first but whenever I click it on its second time there are 2 modals that appear, the previous and the new ones. it stacks every time I click the button.

Answer 1

Problem solved.

function appendHtml(el, str) {
    var div = document.createElement('div');
    div.innerHTML = str;
    $el = el;
    $(el).find(".modal");

    if ($el.lenght){
        var cnt = $(div.children[0]);
        $(".modal").replaceWith(cnt);
    } else {
        el.appendChild(div.children[0]);
        $el.lenght = 1;
    }
}
