我想我越来越接近理解如何将我的网站转向更多 PHP OOP 方法。

我的每个用户都有不同的页面，因为他们对 javascript 生成的网格都有不同的需求。为了可维护性，我可以有一个页面，只需将 php 注入 javascript，如下所示（有点）吗？标准做法是将 php 变量保留在 MySQL 中并根据 $_SESSION['user_id']; 吐出它们吗？只是想知道到目前为止我的想法是否走在正确的道路上？

ORIGINAL GRID
var mygrid;

            function doInitGrid(){  
            mygrid = new dhtmlXGridObject('gridbox');
            var combo=mygrid.getCombo(4);
            combo.put(2, 'Approve / Deny');
            combo.put(1, 'Approve');
            combo.put(0, 'Deny');
            mygrid.setImagePath("../codebase/imgs/");           
            mygrid.setHeader("Submit Date, Manufacturer, Product Category, Progress, Approval Status",null,["text-align:center;","text-align:center;","text-align:center","text-align:center","text-align:center"]);        
            <!--mygrid.attachHeader("#text_filter,#text_filter,#text_filter");-->
            mygrid.setInitWidthsP("10,16,44,18,12");
            mygrid.setColAlign("center,left,left,center,center");
            mygrid.enableAutoWidth(false);
            mygrid.setColTypes("ro,ro,ro,button,coro");
            mygrid.setColSorting("str,str,str,str,str,str");
            mygrid.enableRowsHover(true,'grid_hover');              
            mygrid.setSkin("modern");
            mygrid.init();          
            mygrid.setStyle("font-size:11px;","font-size:11px;","font-size:11px","font-size:11px","font-size:11px");
            mygrid.loadXML("connector.php?hospid=<?php echo $hospid; ?>");
            mygrid.setColumnIds("date,man_name,group,approval_progress, approval_status");          
            var dp = new dataProcessor ("connector.php?hospid=<?php echo $hospid; ?>");     
            dp.init(mygrid);                        
            dhxWins = new dhtmlXWindows();
            dhxWins.setImagePath("../codebase/imgs/");          
            mygrid.attachEvent("onRowSelect", function(id,ind){ 
                 if (ind == 0 || ind == 1 || ind == 2 || ind == 3){  
                dhxWins = new dhtmlXWindows();
                var w1 = dhxWins.createWindow("w1", 60, 60,925, 575);
                dhxWins.setSkin("dhx_web");
                dhxWins.setImagePath("../codebase/imgs/");
                w1.centerOnScreen();
                w1.setText("");
                w1.setModal(false);
                theVar11 = (id);
                w1.attachURL("pop_details.php?var1=" +theVar11);
                return true;
                 };
                 });

MY IDEA FOR OOP GRID
    var mygrid;

                function doInitGrid(){  
                mygrid = new dhtmlXGridObject('gridbox');
                var combo=mygrid.getCombo(4);
                combo.put(2, 'Approve / Deny');
                combo.put(1, 'Approve');
                combo.put(0, 'Deny');
                mygrid.setImagePath("../codebase/imgs/");           
                mygrid.setHeader(<?php $MySQL_results ?>);      
                <!--mygrid.attachHeader("#text_filter,#text_filter,#text_filter");-->
                mygrid.setInitWidthsP("<?php $MySQL_results ?>");
                mygrid.setColAlign("<?php $MySQL_results ?>");
                mygrid.enableAutoWidth(false);
                mygrid.setColTypes("<?php $MySQL_results ?>");
                mygrid.setColSorting("<?php $MySQL_results ?>");
                mygrid.enableRowsHover(true,'grid_hover');              
                mygrid.setSkin("modern");
                mygrid.init();          
                mygrid.setStyle("<?php $MySQL_results ?>");
                mygrid.loadXML("connector.php?hospid=<?php echo $hospid; ?>");
                mygrid.setColumnIds("date,man_name,group,approval_progress, approval_status");          
                var dp = new dataProcessor ("connector.php?hospid=<?php echo $hospid; ?>");     
                dp.init(mygrid);                        
                dhxWins = new dhtmlXWindows();
                dhxWins.setImagePath("../codebase/imgs/");          
                mygrid.attachEvent("onRowSelect", function(id,ind){ 
                     if (ind == 0 || ind == 1 || ind == 2 || ind == 3){  
                    dhxWins = new dhtmlXWindows();
                    var w1 = dhxWins.createWindow("w1", 60, 60,925, 575);
                    dhxWins.setSkin("dhx_web");
                    dhxWins.setImagePath("../codebase/imgs/");
                    w1.centerOnScreen();
                    w1.setText("");
                    w1.setModal(false);
                    theVar11 = (id);
                    w1.attachURL("pop_details.php?var1=" +theVar11);
                    return true;
                     };
                     });

在我看来，（其他人可能会不同意）你提出的建议是一个完全可行的选择。如果你不想在你的 javascript 中包含这么多的 php，你可以使用 phpjson_encode()函数来创建一个初始的 javascript 对象，并使用它的属性而不是 php 回显。例如这样的事情：

var gridOpts = <?php echo json_encode($MySQL_results);?>;
mygrid.setColTypes(gridOpts.colTypes);

我看不懂那个代码，太乱了...

但对于一般用途：

<script type="text/javascript">
    var js_variable = <?php echo json_encode($php_variable); ?>;
</script>

此方法允许您将任何类型的 PHP 变量（资源除外）传递给 JS。
