javascript中的聪明变量

Question

我想在tpl里面的javascript里面使用smarty变量

{literal}
<script language="javascript">
  google.load('visualization','1',{'packages': ['geomap']});
  google.setOnLoadCallback(drawMap);


  function drawMap() {
    var data = new google.visualization.DataTable();
    data.addRows(4);
    data.addColumn('string', 'Location');
    data.addColumn('number', 'Number of links');

{/literal}{foreach from=$last5 item=link name=links key=index}
    data.setValue({$index},0,'{$link.location|replace:'\'':'\\\''}');
    data.setValue({$index},1,{$link.location_count});
{/foreach}{literal}

    var options = {};
    options['dataMode'] = 'regions';
    options['region'] = 'world';

    var container = document.getElementById('map');
    var geomap = new google.visualization.GeoMap(container);

    geomap.draw(data, options);
  };
</script>
{/literal}

你能告诉我一个解决方案吗？

Answer 1

只需在插入smarty变量之前关闭{literal}标记,然后再次重新打开它.

或者使用{ldelim}和{rdelim}作为您从Smarty分配值的代码片段.

Answer 2

{literal}
function doSomething(myNumber){
  var result = myNumber/{/literal}{$myDivider}{literal};
  // rest of code...
}
// more functions...
{/literal}

要么

{literal}
function doSomething(myNumber){
{/literal}
   var result= myNumber/{$myDivider};
{literal}
  // rest of code...
}
// more functions...
{/literal}

要么

function doSomething(myNumber){ldelim}
   var result= myNumber/{$myDivider};
   // rest of code below...
{rdelim}

function doSomeMore(another){ldelim}
   alert('{$myHello}');
   // more code
{rdelim}

或者(使用Smarty 3.x及以上版本,不需要文字等)

function doSomething(myNumber){
   var result = myNumber/{$myDivider};
   // rest of code 
}

在Smarty 3中,左边的大括号旁边有一个空格字符(空格,制表符或换行符),不应再乱用Smarty逻辑了.使用新版本解决的问题:)
