<?php foreach ($viewfields as $view): ?>
if(<?=$view['Attribute']['type'];?>=='text'||<?=$view['Attribute']['type'];?>=='number')
{
$("<input id=input<?=$view['Attribute']['sequence_no'];?> type= 'text' style= 'width:<?=$view['Attribute']['size'];?>px' data-attr=<?=$view['Attribute']['type'];?> ></input><br>").appendTo("#fb_contentarea_col1down21 #<?=$view['Attribute']['sequence_no'];?>");
}

如果我给
$.each(arrayfromPHP,function(i,elem){
}
how do I write the code for $view['Attribute']['type'] in jQuery? elem['Attribute']['type'] won't work I suppose?
如何在 jQuery 中为 $view['Attribute']['type'] 编写代码？我想 elem['Attribute']['type'] 不起作用吗？

elem['Attribute']['type'] does work
elem['Attribute']['type'] 确实有效

var arrayFromPHP = <?php echo json_encode($viewFields) ?>;
$.each(arrayFromPHP, function (i, elem) {
// do your stuff
});
To better understand how the things are wired together (thanks Jonathan Sampson):
为了更好地理解事物是如何连接在一起的（感谢 Jonathan Sampson）：
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript">
var arrayFromPHP = <?php echo json_encode($viewFields) ?>;
$.each(arrayFromPHP, function (i, elem) {
// do your stuff
});
</script>
</head>
<body>
</body>
</html>
You can of course place that SCRIPTtag wherever you want in the page, or you can even reference arrayFromPHPfrom external scripts as arrayFromPHPis declared as global.
您当然可以将该SCRIPT标签放置在页面中的任何位置，或者您甚至可以arrayFromPHP从arrayFromPHP声明为全局的外部脚本中引用。

Given this PHP array:
鉴于此 PHP 数组：
$viewFields = array(
'Attributes' => array(
'type' => 'foo',
'label' => 'bar',
),
'Attributes' => array(
'type' => 'foo',
'label' => 'bar',
),
);
Accessing its elements with jQuery would be done like this:
使用 jQuery 访问它的元素将是这样完成的：
// json_encode() will output:
// {"Attributes":{"type":"foo","label":"bar"}}
$.each(arrayFromPHP, function (i, elem) {
alert(elem.type);
alert(elem.label);
});

The easily way is:
简单的方法是：
PHP:
PHP：
$an_array=array();
$an_array[]='Element 1';
$an_array[]='Element 2';
$an_array[]='Element 3';
$array_js=implode(",",$this->js_pagina); //join elements in a string
JQUERY:
查询：
//Converter
window.array=new String('<?php echo $array_js?>');
window.array=window.js_pagina.split(",");
//Iterator
$.each(window.array, function (i, elem)
{
alert(elem);
});
