Question

我正在尝试使用PHP将JS脚本编写到我的html源文档中。我已经调查了很多其他论坛，但仍然无法确定错误..

我试图嵌入的JS脚本遵循默认YUI图表库脚本的语法。

假设我的php字符串输出（从 echo：$ data-＆gt; dump_yui（$ row_numbers = false，$ col_letters = false，$ sheet = 0，$ table_class ='excel'）生成; ）适合YUI脚本语法的参数r'qd，在我的html doc中嵌入脚本我错了吗？

在HTML中写入JavaScript的PHP：

<?php 
echo "<script language=javascript>";
echo 'document.write("YUI().use('charts',function(Y){var myDataValues = [';
echo $data->dump_yui($row_numbers=false, $col_letters=false, $sheet=0, $table_class='excel');
echo "<br>];<br><br>var styleDef = {series:<br>{Stock:{line:{color:'#898DD5'},marker:{fill:{color:'#eee',alpha:0,wmode:'transparent'},border:{color:'#222',alpha:0,wmode:'transparent'},over:{fill:{color:'#eee'},border:{color:'#000'},width:9,height:9}}},<br>Liability:{line:{color:'#171944'},marker:{fill:{color:'#eee',alpha:0,wmode:'transparent'},border:{color:'#222',alpha:0,wmode:'transparent'},over:{fill:{color:'#eee'},border:{color:'#000'},width:9,height:9}}},<br>Shipment:{line:{color:'#ff0000',alpha:0,wmode:'transparent'},marker:{fill:{color:'#eee',alpha:0,wmode:'transparent'},border:{color:'#ff0000',alpha:0,wmode:'transparent'},over:{fill:{color:'#ff0000',alpha:0,wmode:'transparent'},border:{color:'#000',alpha:0,wmode:'transparent'},width:16,height:16}}},<br>Production:{line:{color:'#FFD700',alpha:0,wmode:'transparent'},marker:{fill:{color:'#eee',alpha:0,wmode:'transparent'},border:{color:'#FFD700',alpha:0,wmode:'transparent'},over:{fill:{color:'#FFD700',alpha:0,wmode:'transparent'},border:{color:'#000',alpha:0,wmode:'transparent'},width:16,height:16}}},<br>Order:{line:{color:'#006400',alpha:0,wmode:'transparent'},marker:{fill:{color:'#eee',alpha:0,wmode:'transparent'},border:{color:'#006400',alpha:0,wmode:'transparent'},over:{fill:{color:'#006400',alpha:0,wmode:'transparent'},border:{color:'#000',alpha:0,wmode:'transparent'},width:16,height:16}}}}};<br>var myAxes={dateRange:{keys:['date'],position:'bottom',type:'category',title:'Date Range',styles:{majorTicks:{display:'none'},label:{rotation:-45,margin:{top:5}},title:{fontSize:'90%'}}}};var mychart=new Y.Chart({dataProvider:myDataValues,interactionType:'planar',render:'#mychart',categoryKey:'Date',styles:styleDef,categoryType:'time',horizontalGridlines:{styles:{line:{color:'#fff'}}},verticalGridlines:{styles:{line:{color:'#fff'}}}});<br>});";
echo '");';
echo "</script>";
?>

（我也试过在没有'document.write'的情况下执行脚本）

我对PHP很绿。有什么想法吗？

_ __ 更新（7月18日，12日）：感谢您的反馈 - 我尝试了所有修复程序，图表仍未呈现，代码为：

<?php 
echo "<script type='text/javascript'>";
echo 'document.write("YUI().use(\'charts\',function(Y){var myDataValues = [';
echo $data->dump_yui($row_numbers=false, $col_letters=false, $sheet=0, $table_class='excel');
echo "\n];\n\nvar styleDef = {series:\n{Stock:{line:{color:'#898DD5'},marker:{fill:{color:'#eee',alpha:0,wmode:'transparent'},border:{color:'#222',alpha:0,wmode:'transparent'},over:{fill:{color:'#eee'},border:{color:'#000'},width:9,height:9}}},<br>Liability:{line:{color:'#171944'},marker:{fill:{color:'#eee',alpha:0,wmode:'transparent'},border:{color:'#222',alpha:0,wmode:'transparent'},over:{fill:{color:'#eee'},border:{color:'#000'},width:9,height:9}}},<br>Shipment:{line:{color:'#ff0000',alpha:0,wmode:'transparent'},marker:{fill:{color:'#eee',alpha:0,wmode:'transparent'},border:{color:'#ff0000',alpha:0,wmode:'transparent'},over:{fill:{color:'#ff0000',alpha:0,wmode:'transparent'},border:{color:'#000',alpha:0,wmode:'transparent'},width:16,height:16}}},<br>Production:{line:{color:'#FFD700',alpha:0,wmode:'transparent'},marker:{fill:{color:'#eee',alpha:0,wmode:'transparent'},border:{color:'#FFD700',alpha:0,wmode:'transparent'},over:{fill:{color:'#FFD700',alpha:0,wmode:'transparent'},border:{color:'#000',alpha:0,wmode:'transparent'},width:16,height:16}}},<br>Order:{line:{color:'#006400',alpha:0,wmode:'transparent'},marker:{fill:{color:'#eee',alpha:0,wmode:'transparent'},border:{color:'#006400',alpha:0,wmode:'transparent'},over:{fill:{color:'#006400',alpha:0,wmode:'transparent'},border:{color:'#000',alpha:0,wmode:'transparent'},width:16,height:16}}}}};<br>var myAxes={dateRange:{keys:['date'],position:'bottom',type:'category',title:'Date Range',styles:{majorTicks:{display:'none'},label:{rotation:-45,margin:{top:5}},title:{fontSize:'90%'}}}};var mychart=new Y.Chart({dataProvider:myDataValues,interactionType:'planar',render:'#mychart',categoryKey:'Date',styles:styleDef,categoryType:'time',horizontalGridlines:{styles:{line:{color:'#fff'}}},verticalGridlines:{styles:{line:{color:'#fff'}}}});<br>});";

**的 _ 更新（7月20日，12日）：

感谢大家的额外反馈。我将一个页面推送到包含三个代码片段的服务器（以一种有点组织的方式）。

......仍然无法压制这个错误！

Answer 1

下面：

echo 'document.write("YUI().use('charts',function(Y){var myDataValues = [';

“图表”撇号存在问题。例如，它应该是：

echo 'document.write("YUI().use("charts",function(Y){var myDataValues = [';

Answer 2

除了其他人提到的内容之外，您的JavaScript代码中还有一大堆<br>个元素，这些元素无效。你将不得不摆脱那些。

Answer 3

别忘了逃避你的单引号：

echo 'document.write("YUI().use(\'charts\',function(Y){var myDataValues = [';

并将<br />替换为\n。

echo "\n];\n\nvar styleDef = {series:\n{Stock:{line:{color:'#898DD5'},marker:{fill:{color:'#eee',alpha:0,wmode:'transparent'},border:{color:'#222',alpha:0,wmode:'transparent'},over:{fill:{color:'#eee'},border:{color:'#000'},width:9,height:9}}},<br>Liability:{line:{color:'#171944'},marker:{fill:{color:'#eee',alpha:0,wmode:'transparent'},border:{color:'#222',alpha:0,wmode:'transparent'},over:{fill:{color:'#eee'},border:{color:'#000'},width:9,height:9}}},<br>Shipment:{line:{color:'#ff0000',alpha:0,wmode:'transparent'},marker:{fill:{color:'#eee',alpha:0,wmode:'transparent'},border:{color:'#ff0000',alpha:0,wmode:'transparent'},over:{fill:{color:'#ff0000',alpha:0,wmode:'transparent'},border:{color:'#000',alpha:0,wmode:'transparent'},width:16,height:16}}},<br>Production:{line:{color:'#FFD700',alpha:0,wmode:'transparent'},marker:{fill:{color:'#eee',alpha:0,wmode:'transparent'},border:{color:'#FFD700',alpha:0,wmode:'transparent'},over:{fill:{color:'#FFD700',alpha:0,wmode:'transparent'},border:{color:'#000',alpha:0,wmode:'transparent'},width:16,height:16}}},<br>Order:{line:{color:'#006400',alpha:0,wmode:'transparent'},marker:{fill:{color:'#eee',alpha:0,wmode:'transparent'},border:{color:'#006400',alpha:0,wmode:'transparent'},over:{fill:{color:'#006400',alpha:0,wmode:'transparent'},border:{color:'#000',alpha:0,wmode:'transparent'},width:16,height:16}}}}};<br>var myAxes={dateRange:{keys:['date'],position:'bottom',type:'category',title:'Date Range',styles:{majorTicks:{display:'none'},label:{rotation:-45,margin:{top:5}},title:{fontSize:'90%'}}}};var mychart=new Y.Chart({dataProvider:myDataValues,interactionType:'planar',render:'#mychart',categoryKey:'Date',styles:styleDef,categoryType:'time',horizontalGridlines:{styles:{line:{color:'#fff'}}},verticalGridlines:{styles:{line:{color:'#fff'}}}});<br>});";
