javastramp 阵列中的 php 变量
原标题:php variable in javascript array

Why is my Javascript array empty? In a while loop I fill a variable ($btext). When I echo $btext everything is shown fine:

但如果我试图填充 Javascript 阵列, 那里没有打印的 。

这就是我如何在 php 中填充变量 $btext :

$btext .= """.${ name_ .$user}."",";

这里的 Javascript 部分 :

var battletext = new Array(<? echo $btext; ?>);

如果我给美元文本下的定义是:

$btext = ""Hallo", "Welt"";

源码看起来是这样的:

<script>
var battletext = new Array("Hallo", "Welt");
</script>
问题回答

你应该使用json编码:

$battletext = array( "Hallo", "Welt" );

html:

<script>
var battletext = <?php echo json_encode( $battletext ); ?>;
</script>

来源 :

<script>
var battletext = ["Hallo", "Welt"];
</script>
