Jquery 将额外的 # 附加到 DOM 对象

Jquery appending extra # to DOM objects

我在IE9中收到以下错误

SCRIPT5022:语法错误,无法识别的表达式:##chart1jquery-2.0.3.min.js,第 4 行字符 14519

我不确定为什么给定下面显示的代码。我显然没有将其添加到 HTML 字符串中,当我在 jqplot 调用中引用它时只有 1。那么,为什么它会弹出此错误呢?

    var HTMLstring = '<!DOCTYPE html>'n';

    newwindow = window.open();

            }
        );
        $('#chart1').bind('jqplotDataClick',
            function (ev, seriesIndex, pointIndex, data) {
                $('#infoclicked').html('series: ' + seriesIndex + ', point: ' + pointIndex + ', data: ' + data + ', pageX: ' + ev.pageX + ', pageY: ' + ev.pageY);
            }
        );
        $('#chart1').bind('jqplotDataUnhighlight',
            function (ev) {
                $('#infomouseover').html('Nothing');
            }
        );
    });
}
jqPlot()不需要

CSS样式选择器来查找Id。它自己处理,因此目前它会两次查找附加##chart1

<script>
    //This will look for #chart1
    $.jqplot('chart1', [data], options );
</script>

jsplot 文档

"通过使用目标的 id 调用 $.jqplot() 插件来创建实际情节"

jqplot 将元素 id 作为参数而不是 id 选择器,因此应该$.jqplot('chart1', $.jqplot('#chart1',等。
