在我的导入照片脚本中,我尝试使用Ajax请求在while循环之后更新进度条(Jquery UI)。
JQueryUI进度条,应该在启动ajax请求之前显示。所以我在while循环执行结束时收到用户反馈...(控制台告诉我这些应用程序运行正常,顺序正确)
我考虑过使用live()或bind(),但我不知道如何测试它......
这是我的jquery代码:
$(function() {
var percent_progressbar=0;
$('#myform').submit(function() {
$('#myform').hide();
$("#text_result").html("Import in progress : <span class='progression'>0/0</span>").show(10, function() {
$("#myprogressbar").progressbar({value:percent_progressbar});
$("#myprogressbar").show(10, function() {
if (jQuery.trim($("#id_src").val()).length!=0) {
// Total number of photos to import
$.ajax({
type : 'POST',
async : false,
url : '/nbphotos.php',
data : 'chem=mydir',
success : function(nbphotos){
if (nbphotos>0){
$(".progression").html("0"+" / "+nbphotos);
var finish=false;
var nb_photos_imported=0;
var ajax_done = false;
var resultat_ajax="";
// Variables envoyées en Ajax
var datas = desvariables;
while (nb_photos_imported < nbphotos) {
ajax_done = false;
$.ajax({
type : 'GET',
async : false,
url : '/traitement.php',
data : datas,
success : function(resultat){
resultat_ajax=resultat;
ajax_done=true;
nb_photos_imported++;
}
});
if (ajax_done==true){
if (resultat_ajax=="ok") {
percent_progressbar = Math.floor(nb_photos_imported*100/nbphotos);
$("#myprogressbar").progressbar("option", "value", percent_progressbar);
console.info("Succès ajax (resultat : OK) : "+percent_progressbar);
$(".progression").html(nb_photos_imported+" / "+nbphotos);
} else {
finish=true;
$("#text_result").html(ajax_done);
return false;
}
} else {
// ajax error => exit the while
console.info("Ajax execution error "+nb_photos_imported);
return false;
}
} // While
if (finish==true) {
$("#myprogressbar").hide('slow');
$('#text_result').html("Import of "+nb_photos_imported+" photos done.");
}
} else{
$("#text_result").html("No photo to import.");
$("#myprogressbar").hide(10);
$('#myform').show("slow");
}
}
});
}
});
}); // callback #text_result.show()
return false;
});
});
答案 0 :(得分:0)
这是我的新代码。控制台日志显示百分比的进度,照片是导入的,但我仍然在最后显示。如果我在循环中的某个地方放置一个断点与我的调试工具,显示是刷新的,一切都很好......

$("#myprogressbar").show();
