在與php常量相關的javascript中包含條件

Question

我會知道如何在js中包含條件。 就像您在我的表格中看到的那樣，此常量MODE_B2B_B2C; 如何在js中做同樣的事情。

k

         <table width="100%" cellpadding="5" cellspacing="0" border="0">
           <tr>
        if (MODE_B2B_B2C == 'true') {
          $content .= '
                          <td>' . $this->app->getDef('table_heading_customers_group') . '</td>
                      ';
        }
</tr>
</table>

      $output = <<<EOD
<script type="text/javascript"><!--
  var quantitydiscount_row = $i;

  function addQuantityDiscountValue() {


   //customers_group_id
    html += '<td>';
    html += '  <select name="products_quantitydiscount[' + quantitydiscount_row + '][customers_group_id]" class="form-control">{$customers_group_name}</select>';
    html += '</td>';


    quantitydiscount_row++;
  }
</script>
<br />
EOD;

您可以使用模板字符串：

 let myVal = 123; function condition(input) { if (input > 10) return "foo"; return "bar"; } let str = `This will output ${myVal} * 2 = ${myVal * 2}. Condition: ${condition(2)} Condition: ${condition(20)} `; console.log(str);
