Question

我正在我的网站上测试一个条形码但由于某种原因，没有出现代表条形码的class =“b128”的div。如果我在另一个网站上测试相同的源代码，它会显示出来但具有不同的样式。

有谁知道如何让这个源代码显示出来并同时保留原始样式？

<style>
div.b128{
border-left: 1px black solid;
height: 60px;
}   
</style>

<?php
global $char128asc,$char128charWidth;
$char128asc=' !"#$%&\'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~';                 
$char128wid = array(

Answer 1

您并未关闭大部分代码。试试这个：

    $html = "<table cellpadding=0 cellspacing=0><tr>";
    for ($x = 0; $x < strlen($w); $x += 2)                         // code 128 widths: black border, then white space
        $html .= "<td><div class=\"b128\" style=\"border-left-width:{$w[$x]};width:{$w[$x+1]}\"></div></td>";
    return "$html</tr><tr><td  colspan=" . strlen($w) . " align=center><font family=arial size=2><b>$text</b></font></td></tr></table>";

div和class没有显示
