PHP进度条

    {</span><span>echo</span><span>$html</span>;
        <span>$i</span> = <span>0</span>;
        <span>$sum</span> = count(<span>$data</span>);
        <span>if</span>(<span>$sum</span> == <span>0</span>){
            <span>echo</span><span>"数据出错"</span>;
            <span>return</span>;
        }

                        <span>$ret</span> = <span>$this</span>->btrManger_m->inserts100(<span>$tdata</span>); <span>//一次插入100条</span><span>if</span>(<span>$ret</span>){

                        <span>else</span>{ <span>//出错 终止</span><span>break</span>;
                        }
                        <span>$tdata</span> = <span>array</span>();
                    } 
            }
        } <span>catch</span> (<span>Exception</span><span>$e</span>) {
            <span>echo</span><span>$e</span>; 
            <span>return</span>;
        }
        <span>$resultStr</span> = <span>"'共计"</span>.<span>$sum</span>.<span>"条记录,成功操作完成"</span>.<span>$i</span>.<span>"条！'"</span>;
        <span>echo</span><span>""</span>;
    }</code>

前端用bootstrap的进度条实现:

<code><span><span>function</span><span>setProgressBar</span><span>(width)</span>{</span>
    str=width+<span>"%"</span>;
    $(<span>'.progress-bar'</span>).attr(<span>'aria-valuenow'</span>,str).css(<span>'width'</span>,str) .html(str);
    <span>if</span>(width == <span>100</span>){
        $(<span>'#idInsertResult'</span>).html(<span>"数据操作完成!"</span>);
    }
}</code>

<code><<span>div</span><span>class</span>=<span>"progress"</span>>
    <<span>div</span><span>class</span>=<span>"progress-bar progress-bar-info progress-bar-striped active"</span> role=<span>"progressbar"</span> aria-valuenow=<span>"0"</span> aria-valuemin=<span>"1"</span> aria-valuemax=<span>"100"</span> style=<span>"width: 3%;"</span>>
               <span>0</span>%
    <!--<span-->div>
<!--<span-->div></code>
