未定义的子程序＆main :: ThrowTemplateError

Question

following is my template code : 以下是我的模板代码：

<html>
<head>
<style>

.table
{
    display:table;
    border-collapse:separate;
    border-spacing:2px;
}
.thead
{
    display:table-header-group;
    color:white;
    font-weight:bold;
    background-color:grey;
}
.tbody
{
    display:table-row-group;
}

.tr
{
    display:table-row;
}
.td
{
    display:table-cell;
    border:1px solid black;
    padding:1px;
}
.tr.editing .td INPUT
 width:100px;
}
</style>
<script type = "text/javascript" src = "jquery.min.js"></script>
<script>
var counter = 0;
var txt1 = "group_save";
function addNew() {
// Get the main Div in which all the other divs will be added
var mainContainer = document.getElementById('mainContainer');
// Create a new div for holding text and button input elements
var newDiv = document.createElement('div');
// Create a new text input
var newText = document.createElement('input');
newText.type = "input";
newText.name = txt1+counter;
//newText.value = counter;
// Create a new button input
var newDelButton = document.createElement('input');
newDelButton.type = "button";
newDelButton.value = "Delete";
// Append new text input to the newDiv
newDiv.appendChild(newText);
// Append new button input to the newDiv
newDiv.appendChild(newDelButton);
// Append newDiv input to the mainContainer div
mainContainer.appendChild(newDiv);
counter++;
// Add a handler to button for deleting the newDiv from the mainContainer
newDelButton.onclick = function() {
mainContainer.removeChild(newDiv);
}
}
   function edit(element){
  var tr = jQuery(element).parent().parent();
    if(!tr.hasClass("editing")) {
            tr.addClass("editing");
            tr.find("DIV.td").each(function(){
                    if(!jQuery(this).hasClass("action")){
                            var value = jQuery(this).text();

                            jQuery(this).text("");
                            jQuery(this).append('<input type="text" value="'+value+'" />');

                    } else {
                            jQuery(this).find("BUTTON").text("save");
                    }
            });
    } else {
            tr.removeClass("editing");
            tr.find("DIV.td").each(function(){
                    if(!jQuery(this).hasClass("action")){
                            var value1 = jQuery(this).find("INPUT").val();
                            alert(value1);
                            jQuery(this).text(value1);
                            jQuery(this).find("INPUT").remove();
                    } else {
                            jQuery(this).find("BUTTON").text("edit");
                    }

updated : 更新：

error --- Undefined subroutine &main::ThrowTemplateError called at /var/www/html/centralbugzilla/groups.cgi line 24. 错误---未定义的子程序＆main :: ThrowTemplateError在/var/www/html/centralbugzilla/groups.cgi第24行调用。

line no 24 is : $template->process("list/group.html.tmpl",$vars) || 第24行是：$ template-> process（“ list / group.html.tmpl”，$ vars）|| ThrowTemplateError($template->error()); ThrowTemplateError（$ template-> error（））;

Firstly, you shouldn't assume that people will just know which templating system you are using. 首先，您不应该假设人们会知道您使用的是哪个模板系统。 It looks to me like you are using the Template Toolkit, but there are many template engines for Perl. 在我看来，您正在使用模板工具包，但是Perl有很多模板引擎。

Secondly, the template is a complete red herring here. 其次，此处的模板是完整的红色鲱鱼。 The problem is in your Perl code. 问题出在您的Perl代码中。 When the template can't be processed successfully, your code calls a function called ThrowTemplateError , but Perl can't find that function anywhere. 当无法成功处理模板时，您的代码将调用一个名为ThrowTemplateError的函数，但Perl在任何地方都找不到该函数。 Where is that function defined? 该功能在哪里定义？

(Ok, I suppose it could look like the problem is in your template and not the code. There's some error in your template which means that TT can't process it and therefore the missing function is called. So fixing the error in your template will mean that the missing function no longer gets called. But it's still missing. And it will be a problem again the next time you accidentally break your template. So best to fix it now, I think.) （好吧，我想这似乎是您的模板而不是代码中的问题。您的模板中存在一些错误，这意味着TT无法处理它，因此调用了缺少的函数。因此，请修复模板中的错误表示丢失的函数不再被调用。但是它仍然丢失。下次您不小心破坏模板时，这将再次成为问题。因此，我认为现在最好对其进行修复。）
