javascript中的print_r

function print_r(theObj) {
var retStr = '';
if (typeof theObj == 'object') {
retStr += '<div style="font-family:Tahoma; font-size:7pt;">';
for (var p in theObj) {
if (typeof theObj[p] == 'object') {
retStr += '<div><b>['+p+'] => ' + typeof(theObj) + '</b></div>';
retStr += '<div style="padding-left:25px;">' + print_r(theObj[p]) + '</div>';
} else {
retStr += '<div>['+p+'] => <b>' + theObj[p] + '</b></div>';
}
}
retStr += '</div>';
}
return retStr;
}

调用函数输出的代码如下：

$(function(){
$.getJSON("http://api.zuosa.com/statuses/public_timeline.json?callback=?", function(data) {
$("#debug").html(print_r(data));
});

})

插件代码如下：

(function($){
$.fn.print_r = function(json){
return $(this).each(function(e){
$(this).html(_print_r(json));
})
}
function _print_r(theObj) {
var retStr = '';
if (typeof theObj == 'object') {
retStr += '<div style="font-size:12px;">';
for (var p in theObj) {
if (typeof theObj[p] == 'object') {
retStr += '<div><b>['+p+'] => ' + typeof(theObj) + '</b></div>';
retStr += '<div style="padding-left:25px;">' + _print_r(theObj[p]) + '</div>';
} else {
retStr += '<div>['+p+'] => <b>' + theObj[p] + '</b></div>';
}
}
retStr += '</div>';
}
return retStr;
}
$.print_r = function(json){
return _print_r(json);
}
})(jQuery);
