php 的一维数组 如何转为 js的数组 的方法

Thinkphp : $this -> the_ipsort = json_encode(M($this -> ipsort) -> getField('name',true)) ;

php文件：echo json_encode($arr);  

ajax接收：var ret=eval("("+xmlhttp.responseText+")");

非ajax接收：<script>var citys=eval(<?php echo json_encode($citys) ?>);</script>

引用：ret[row]['name'];

jquery ui　有一个自动完成的功能，但里面需要使用一个数据格式为

var availableTags = [
"ActionScript",
"AppleScript",
"Asp",
"BASIC",
"C",
"C++",
"Clojure",
"COBOL",
"ColdFusion",
"Erlang",
"Fortran",
"Groovy",
"Haskell",
"Java",
"JavaScript",
"Lisp",
"Perl",
"PHP",
"Python",
"Ruby",
"Scala",
"Scheme"
];

使用上面的方式就可以生成　［ｘｘｘｘ］每个值都会有引号

function autoipsort()
{
var availableTags = eval({$the_ipsort}) ;
$( "#sort" )
// don't navigate away from the field on tab when selecting an item
.bind( "keydown", function( event ) {
if ( event.keyCode === $.ui.keyCode.TAB &&
$( this ).data( "autocomplete" ).menu.active ) {
event.preventDefault();
}
})
.autocomplete({
minLength: 0,
source: availableTags
});
}
