出于某种原因,我很难在JSON / jquery创建的元素上实现draggable(jquery或draggabilly)。
这是我的jQuery以及JSON。
var setTotal = function (){
var total = 0;
$('.block').each(function(){
total = total+parseInt($(this).data('cost'));
});
$('.totalSum').html(total);
};
window.onload = function(){
$.getJSON( "ajax/test.json", function( data ) {
$.each( data.createButton, function( key, val ) {
var button = $('<button class="btn" id="' + val.name +'" style="background: ' + val.color + '">' + val.name + '</button>');
button.on("click", function(){
//console.log("button " + val.name + " was clicked!");
var block = $('<div id="draggable" class="block ' + val.name + '-piece">'+ val.name + '<div class="close">-</div></div>');
block.data('cost', val.cost);
block.on("click", ".close", function(){
$(this).parent().remove();
// call set total to refresh it when item is removed
setTotal();
});
$('#boxes').append(block);
// call set total to calculate total blocks' cost
setTotal();
});
$('#field').append(button);
});
});
};
这就是它在html文档中的调用方式;
<!-- Grab Google CDN's jQuery -->
<script src="https://code.jquery.com/jquery-2.1.4.min.js" type="text/javascript"></script>
<!-- Grab draggable -->
<script src="//cdnjs.cloudflare.com/ajax/libs/draggabilly/1.2.0/draggabilly.pkgd.min.js"></script>
<!-- My own scripts -->
<script src="js/main.js" type="text/javascript"></script>
<script>
var $draggable = $('#draggable').draggabilly({
// options...
});
</script>
<!-- End scripts -->
现在由于某种原因,我无法定位ID(仅用于测试),也不能定位块变量的类(块)。有谁知道为什么? draggable可以与页面上的任何其他元素一起使用。

两件事:
id="draggable"
附加多个元素。 Ids应该是独一无二的。draggabilly
。需要调用Draggabilly:
就个人而言,我会编写类似这样的代码:
window.onload = function() {
var draggabilly_options = {
// options...
};
function create_button(key, val) {
$('<button/>', {
'id': val.name,
'class': 'btn',
'style': 'background-color:' + val.color,
'html': val.name,
})
.appendTo("#field")
.on('click', create_block.bind(val));
}
function create_block() {
$('<div/>' {
'class': 'block ' + this.name + '-piece',
'html': this.name + '<div class="close">-</div>'
})
.appendTo('#boxes')
.draggabilly(draggabilly_options) //invoke draggabilly on the div.block just added
.data('cost', this.cost)
.find('.close')
.on('click', close);
}
function close() {
$(this).closest(".block").remove();
setTotal();
}
function setTotal() {
var total = 0;
$(".block").each(function() {
total += parseInt($(this).data('cost'));
});
$('.totalSum').html(total);
};
$.getJSON( "ajax/test.json", function(data) {
$.each(data.createButton, create_button);
setTotal();
});
//You need this only if the page loads with any "draggable" blocks already in place.
$("#boxes .block").draggabilly(draggabilly_options);
};

感谢您的回复。我从您发布的代码中得到了一些建议,并将其写成这样;
// Start this after window is loaded
window.onload = function(){
// Init draggabilly
var draggabilly_options = {
// Dragabilly options
containment: '#boxes',
grid: [ 100, 100 ]
};
并在按钮点击功能中进一步定义,如此;
button.on("click", function(){
var block = $('<div id="block-' + val.id + '" class="block ' + val.name + '-piece"></div>');
var close = $('<div class="close">-</div>');
$(block).append(close);
block.data('cost', val.cost);
block.draggabilly(draggabilly_options);
这似乎为我解决了!感谢您的帮助和解答,他们解决了我的问题:)
