[英]firebug javascript/jquery debugging
I have the following script which I want to debug: 我有以下要调试的脚本:
function getTabFrame() {
$.ajax({
url: 'get_tab_frame.aspx?rand=' + Math.random(),
type: 'GET',
dataType: 'json',
error: function(xhr, status, error) {
//alert('Error: ' + status + '\nError Text: ' + error + '\nResponse Text: ' + xhr.responseText);
},
success: function( data ) {
$( "#divTabsDropdown" ).empty();
$.each( data, function( index, item ) {
// create tabs with custom ids
$( "#tabs" ).tabs( "add", "get_tab_content.aspx?tab=" + item.key, item.value)
.find( ">ul>li:last" )
.attr( "id", "tab_group_" + item.key );
// creates the buttons
$( "#divTabsDropdown" ).append( "<div class='item custom_group' id='tab" + item.ordering + "'>" + item.value + "</div>" );
// link buttons with tabs
$("#tab" + item.ordering).live('click', function() {
$("#tabs").tabs( "select" , $( "#tab_group_" + item.key ).index() );
});
});
}
});
}
If I add a breakpoint to $.ajax({
, and run the debugging, that is where it stops. If I then hover over data
in the line success: function( data ) {
, no popup is displayed so no value can be seen. I want to see what is inside data
. 如果我在
$.ajax({
添加一个断点,然后运行调试,它将在此停止。如果然后我将鼠标悬停在success: function( data ) {
行中的data
上success: function( data ) {
,则不会显示任何弹出窗口,因此看不到任何值我想看看里面的data
是什么。
So I thought "maybe I need to press F10 a couple of times so firebug can actually run enough of the javascript/jquery before a value is displayed". 因此,我认为“也许我需要按几次F10键,以便Firebug在显示值之前实际上可以运行足够的javascript / jquery”。 So I did, I got to the end of the function, hovered the mouse over
data
in success: function( data ) {
, and again, no popup, therefore no data is displayed. 所以我做到了,我到了函数的结尾,
success: function( data ) {
将鼠标悬停在data
上success: function( data ) {
,同样,没有弹出窗口,因此没有数据显示。
What am I doing wrong? 我究竟做错了什么? Why can't I see what is held within
data
? 为什么看不到
data
?
I have installed firebug plus firequery in firefox. 我已经在firefox中安装了firebug和firequery。
data
is defined as a parameter of your success callback function. data
定义为成功回调函数的参数。 If you want to see it's value, you have to be on a line in the implementation of this function. 如果要查看它的价值,则必须在执行此功能时保持一致。
You should put the breakpoint on the first line of your success callback, which is 您应该将断点放在成功回调的第一行,即
$( "#divTabsDropdown" ).empty();
If it's never hit, it's that you request is still pending or ended up in an error. 如果它从未被命中过,那就是您的请求仍处于待处理状态或最终导致错误。 In this last case, error callback will be called.
在这最后一种情况下,将调用错误回调。
