How to pass `$(this)` to Slick.js plugin (and create multiple carousels with a loop)

问题

How do I pass $(this).find('.option') and $(this).find('.prev_next') to Slick.js? The following produces: Syntax error, unrecognized expression: [object Object]:not(.slick-cloned) in jquery-2.1.0.js:1429

http://jsfiddle.net/frank_o/Lr30ngo1/4/

$('.test').each(function () {
    var option = $(this).find('.option'),
        prev_next = $(this).find('.prev_next');

    $(this).slick({
        slide: option,
        appendArrows: prev_next,
        prevArrow: '<a>Previous</a>',
        nextArrow: '<a>Next</a>'
    });
});

<div class="test">
    <div class="prev_next"></div>
    <div class="option">
        <p>Test</p>
    </div>
    <div class="option">
        <p>Test</p>
    </div>
</div>
<div class="test">
    <div class="prev_next"></div>
    <div class="option">
        <p>Test</p>
    </div>
    <div class="option">
        <p>Test</p>
    </div>
</div>
<div class="test">
    <div class="prev_next"></div>
    <div class="option">
        <p>Test</p>
    </div>
    <div class="option">
        <p>Test</p>
    </div>
</div>

Without something like this, Slick.js would freak out and produce a whole bunch of broken prev/next links: http://jsfiddle.net/frank_o/Lr30ngo1/3/

Here is the expected output with only one .test div: http://jsfiddle.net/frank_o/Lr30ngo1/6/

Looks like you don't need to pre-create the jQuery collections but instead just pass the selector strings as the values for the slide and appendArrows

You also need to uniquely identify the prev_next container and the options some how since slick wants a selector, and not an element/collection for those parameters.

See the fixed jsFiddle here: http://jsfiddle.net/81t4pkfa/2/

Fixed code follows: (this version uses your original markup, and dynamically assigns ID to each carousel to keep it "clean")

$('.test').each(function (idx, item) {
   var carouselId = "carousel" + idx;
   this.id = carouselId;
   $(this).slick({
       slide: "#" + carouselId +" .option",
       appendArrows: "#" + carouselId + " .prev_next",
       prevArrow: '<a>Previous</a>',
       nextArrow: '<a>Next</a>'
   });
});

.prev_next a { display: inline-block; width:80px; text-align:center; margin: 2px; border: 0; padding: 4px; background-color: #666; color: #fff; }
