未为 php 生成的表单加载 Javascript

Question

我用的是phpBMS，做了一个表格，类似于sample provided。

使用提供的输入字段，我制作了一个包含两个项目和一个复选框的基本下拉列表。

我希望在选择下拉框中的选项之一时自动选中复选框。

Jens F，为我提供了如何在 javascript here 中执行此操作的解决方案。

但是，由于某种原因，我无法执行 javascript。

我在一个名为 checkpaid.js 的文件中有 javascript，该文件包含在我的表单中。使用 firebug 我可以看到 javscript 文件已被提取，并出现在脚本列表中，但它绝对从未执行过。

当它明确包含在页面中时，我如何开始弄清楚它为什么不执行？

Here 是为现有表单提供的 javascript 示例，如果单击单选按钮，它将执行操作。

这是我当前的表单和 javascript：

<?php
error_reporting(E_ALL);
ini_set('display_errors', TRUE);
ini_set('display_startup_errors', TRUE);

    include("../../include/session.php");
    include("include/tables.php");
    include("include/fields.php");

    include("include/sales.php");

    if(!isset($_GET["backurl"]))
        $backurl = NULL;
    else{
        $backurl = $_GET["backurl"];
        if(isset($_GET["refid"]))
            $backurl .= "?refid=".$_GET["refid"];
    }

    $thetable = new sales($db, "tbld:490cf2d1-1c72-7b99-461d-b1b8e68553c4");
    $therecord = $thetable->processAddEditPage();

    if(isset($therecord["phpbmsStatus"]))
        $statusmessage = $therecord["phpbmsStatus"];

    $pageTitle = "Sales";

    $phpbms->cssIncludes[] = "pages/menus.css";
    $phpbms->jsIncludes[] = "modules/base/javascript/menu.js";
    $phpbms->jsIncludes[] = "modules/micro hospitality/javascript/checkpaid.js";

    $phpbms->onload[] = "initializePage()";

        $theform = new phpbmsForm();

        $theinput = new inputSmartSearch($db, "chooseguests", "Choose Guests",NULL, "Choose Guest", TRUE, NULL, NULL, TRUE, $required=true);
        $theinput->setAttribute("class","important");
        $theform->addField($theinput);

        $theinput = new inputSmartSearch($db, "chooseproducts", "Choose Product",NULL, "Choose Product", TRUE, NULL, NULL, TRUE, $required=true);
        $theinput->setAttribute("class","important");
        $theform->addField($theinput);

        $theinput = new inputField("quantity",$therecord["quantity"],"Quantity",true, NULL, 1);
        $theinput->setAttribute("class","important");
        $theform->addField($theinput);

        $theinput = new inputBasicList("type",$therecord["paymenttype"],array("Cash"=>"cash","Credit"=>"credit"), "Payment Type");
        $theinput->setAttribute("class","important");
        $theform->addField($theinput);

        $theinput = new inputCheckbox("paid", $therecord["paid"], "Paid");
        $theform->addField($theinput);

        $theinput = new inputField("receiptno",$therecord["receiptno"],"Receipt No",true, NULL, 10);
        $theinput->setAttribute("class","important");
        $theform->addField($theinput);

        $thetable->getCustomFieldInfo();
        $theform->prepCustomFields($db, $thetable->customFieldsQueryResult, $therecord);
        $theform->jsMerge();

    include("header.php");

?><div class="bodyline">

    <?php $theform->startForm($pageTitle)?>

    <div id="leftSideDiv">
        <fieldset>

            <p class="big"><?php $theform->showField("receiptno"); ?></p>


        </fieldset>

    </div>
    <?php
        $theform->showGeneralInfo($phpbms,$therecord);
        $theform->endForm();
    ?>
</div>
<?php include("footer.php");?>


------------------
checkpaid.js: 

window.addEvent('domready', function(){
  $('type').addEvent('change',function(){
    if($(this).get('value') == 'credit') {
      $('paid').set('checked','checked');
    } else {
      $('paid').removeProperty('checked');
    }
  });
});
alert("loaded");

您错过的页面是否正在加载；之后

<?php $theform->startForm($pageTitle)?>
