有没有更有效的方法来编写以下内容?我需要遍历 objList 并将 UnqKey 传递给 wfrmPrint。成功后,我必须遍历页面。我通过传递一个整数并检查它是否小于长度来遍历页面和取消键。我尝试使用取自http://www.tentonaxe.com/index.cfm/2011/9/22/Using-jQuerywhen-with-a-dynamic-number-of-objects的 .when.apply ,但它正在加载unqkeys 然后是页面。
//sample objList
[
{
"UnqKey": 1,
"Pages": [
"wfrmSet1Page1.aspx",
"wfrmSet1Page2.aspx"
]
},
{
"UnqKey": 2,
"Pages": [
"wfrmSet2Page1.aspx",
"wfrmSet2Page2.aspx",
"wfrmSet3Page2.aspx",
"wfrmSet4Page2.aspx"
]
}
]
function Loop(iListIndex) {
var obj = objList[iListIndex];
if (iListIndex < objList.length) {
jQuery.ajax({
type: "GET",
url: 'wfrmPRINT.aspx?action=LoadSession&UnqKey=' + obj.UnqKey, //load session that is used in wfrmSet1Pages.. or wfrmSet2Pages..
success: function () {
AddPages(obj, iListIndex, 0);
}
})
} else {
alert('Done');
}
}
function AddPages(obj, iListIndex, iPageIndex) {
if (iPageIndex < obj.Pages.length) {
jQuery.ajax({
type: "GET",
url: obj.Pages[iPageIndex] + '?Print=1', //load html
async: true,
success: function (html) {
iPageIndex++
AddPages(obj, iListIndex, iPageIndex);
},
error: function () {
alert('Failed!');
iPageIndex++
AddPages(obj, iListIndex, iPageIndex);
}
});
} else {
iListIndex++
Loop(iListIndex);
}
}
