javascript - TypeError : o. 元素未定义 - jquery ui

Question

我正在使用 jquery-ui。 2 周后我无法解决这个问题。

我不知道为什么在点击 slider 后出现这个错误:

控制台火狐:

TypeError: o.element is undefined[Learn More]  jquery-ui.min.js:6:6058

控制台 chrome:

jquery-ui.min.js:6 Uncaught TypeError: Cannot read property 'toggleClass' of undefined

    $(document).ready(function(){

        $( "#slider" ).slider({
            range: true,
            min: -10000000,
            max: -1000,
            values: [ -8000000, -2000 ],
            slide: function(event, ui) {
                $(".amount .min-price").text(addCommas (ui.values[1]*-1) + " ریال ");
                $(".amount .max-price").text(addCommas (ui.values[0]*-1) + " ریال ");
            }
        });

        $(".amount .min-price").text(addCommas ($("#slider").slider( "values", 1 )*-1  ) + " ریال ");
        $(".amount .max-price").text(addCommas ($("#slider").slider( "values", 0 )*-1  ) + " ریال ");
        // Hover states on the static widgets
        $( "#dialog-link, #icons li" ).hover(
            function() {
                $( this ).addClass( "ui-state-hover" );
            },
            function() {
                $( this ).removeClass( "ui-state-hover" );
            }
        );

    });

</script>

我的 HTML 代码:

<div class="col-md-12">
    <div id="slider" class="ui-slider ui-corner-all ui-slider-horizontal ui-widget ui-widget-content">
        <div class="ui-slider-range ui-corner-all ui-widget-header">

        </div>
        <span tabindex="1" class="ui-slider-handle ui-corner-all ui-state-default">

        </span>
        <span tabindex="2" class="ui-slider-handle ui-corner-all ui-state-default" >

        </span>
    </div>
</div>

//used in slider
function addCommas(nStr){
    nStr += '';
    x = nStr.split('.');
    x1 = x[0];
    x2 = x.length > 1 ? '.' + x[1] : '';
    var rgx = /(\d+)(\d{3})/;
    while (rgx.test(x1)) {
        x1 = x1.replace(rgx, '$1' + ',' + '$2');
    }
    return x1 + x2;
}

我删除了额外的代码，但我得到了同样的错误:

它在 jsfiddle 上工作正常!!!:

.toggleClass() is a function of jQuery, so if you're getting an errorthat it's undefined, then it's possible another version of jQuery maybe loaded elsewhere. Or it's not being loaded at all.

Answer 1

我遇到了这个问题，并解决了它。

我不小心将 slider 设置为未定义的值。那时，没有产生任何错误。

但是，当我稍后尝试移动 slider 时，出现错误 o.element is undefined。

当我将 slider 设置为合适的值时，问题就消失了。
