jQuery 延迟和对话框 [英] jQuery Deferred and Dialog box
问题描述
function ValidateField(){var bAllow=true;//这里有一些检查if (bAllow == true && apl.val().trim() == ""){显示对话框()；showDialog().done(function() {返回真；//想返回真，但不成功}).失败(函数(){返回假；//想返回false，但不成功});返回假；//停止执行到下一行}返回 bAllow;//成功返回 }函数 showDialog(){var def = $.Deferred();var modPop = '<div id="diaCom" title="信息?"><p>东西</p></div>';$("#diaCom").remove();$(modPop).appendTo('body');$("#diaCom").dialog({可调整大小:假，可拖动:假，高度:150，宽度:300，模态:真，纽扣: {好的":函数(){def.resolve();$(this).dialog("close");},取消":函数(){def.reject();$(this).dialog("close");}}});返回 def.promise();}//点击时if (validateField() == true){//做一点事}别的{//做一点事}大家好，有机会返回值吗?我希望通过 showDialog().done() 返回 true 和 false 并为 validatefield() 函数失败，但它不能按我想要的方式工作，我无法分配给 bAllow 因为我已经有一个 return false 可以保留执行下一行的对话框，知道吗?或者这样做是否正确?
嗯，这行得通.
你的对话函数... showDialog()
功能确认(问题){var defer = $.Deferred();$('').html(问题).对话({自动打开:真，模态:真，title: '确认',纽扣: {是":函数(){defer.resolve(true);//回答$(this).dialog(关闭");},否":函数(){defer.resolve(false);//回答$(this).dialog(关闭");}},关闭:函数(){$(this).remove();//从DOM中删除这个对话框div}});返回 defer.promise();}
然后是您使用该函数的代码...
function onclick(){var question = "你想发动战争吗?";确认(问题).然后(功能(答案){如果(答案){alert("这显然是" + answer);//TRUE} 别的 {alert("然后是" + answer);//FALSE}});}这对大多数人来说似乎是错误的.但总有一些情况，你就是不能不从 JQuery Dialog 返回.
这将基本上模仿 confirm() 函数.但是代码很丑，确认框看起来很漂亮:)
我希望这能帮助一些人.

Bootstrap 3 解决方案
**我现在正在使用 [NakuPanda's][1] 引导程序库，它运行得非常好.基本上与 JQueryUI 相同，但在 Bootstrap UI 中.
function bsConfirm(question) {var defer = $.Deferred();BootstrapDialog.show({类型:BootstrapDialog.TYPE_PRIMARY，title: '确认',消息:问题，closeByBackdrop:假，closeByKeyboard: 假，可拖动:真实，纽扣: [{标签:'是'，动作:功能(对话框){defer.resolve(true);dialog.close();}}, {标签:'不'，动作:功能(对话框){defer.resolve(false);dialog.close();}}],关闭:功能(对话框){对话框删除()；}});返回 defer.promise();}功能 bsAlert(错误，消息){BootstrapDialog.show({类型:错误?BootstrapDialog.TYPE_DANGER : BootstrapDialog.TYPE_SUCCESS,标题:错误?错误":成功"，消息:消息，closeByBackdrop:假，closeByKeyboard: 假，可拖动:真实，纽扣: [{标签:'好的'，行动:功能(d){d.关闭();}}]});}并使用它(几乎相同的方式)
bsConfirm(你确定 Bootstrap 是你想要的吗?").then(function (answer) {如果(答案){bsAlert(干得好！你的选择是正确的");} 别的 {bsAlert(我不喜欢你！");}});function ValidateField(){
var bAllow= true;
//some checking here
if (bAllow == true && apl.val().trim() == "")
{
showDialog();
showDialog().done(function() {
return true; // wanna return true, but not success
}).fail(function() {
return false; //wanna return false, but not success
});
return false; //stop it to execute to next line
}
return bAllow; //success return }
function showDialog(){
var def = $.Deferred();
var modPop = '<div id="diaCom" title="Information?"><p>something something</p></div>';
$("#diaCom").remove();
$(modPop).appendTo('body');
$("#diaCom").dialog({
resizable: false,
draggable: false,
height:150,
width:300,
modal: true,
buttons: {
"Ok": function() {
def.resolve();
$(this).dialog("close");
},
"Cancel": function() {
def.reject();
$(this).dialog("close");
}
}
});
return def.promise();
}
//on click
if (validateField() == true){
//do something
}else{
//do something
}
hi everyone, any chance to return the value? I wish to return the true and false through showDialog().done() and fail for validatefield() function, but it not working as what I want, I can't assign to bAllow as I had already have a return false to hold the dialog to execute its next line, any idea? Or it is correct to do like these?
Well, This can work.
Your dialog function... showDialog()
function confirmation(question) {
var defer = $.Deferred();
$('<div></div>')
.html(question)
.dialog({
autoOpen: true,
modal: true,
title: 'Confirmation',
buttons: {
"Yes": function () {
defer.resolve(true); //answer
$(this).dialog("close");
},
"No": function () {
defer.resolve(false); //answer
$(this).dialog("close");
}
},
close: function () {
$(this).remove(); //removes this dialog div from DOM
}
});
return defer.promise();
}
and then the code where you use the function...
function onclick(){
var question = "Do you want to start a war?";
confirmation(question).then(function (answer) {
if (answer) {
alert("this is obviously " + answer);//TRUE
} else {
alert("and then there is " + answer);//FALSE
}
});
}
This may seem wrong for most people. But there is always some situations where you just can't go without return from JQuery Dialog.
This will basically mimic the confirm() function. But with ugly code and a nice confirm box look :)
I hope this helps some people out.

EDIT: Bootstrap 3 Solution
**I am now using [NakuPanda's][1] bootstrap library, It works really well. Basically the same as with JQueryUI but in the Bootstrap UI.
function bsConfirm(question) {
var defer = $.Deferred();
BootstrapDialog.show({
type: BootstrapDialog.TYPE_PRIMARY,
title: 'Confirmation',
message: question,
closeByBackdrop: false,
closeByKeyboard: false,
draggable: true,
buttons: [{
label: 'Yes',
action: function (dialog) {
defer.resolve(true);
dialog.close();
}
}, {
label: 'No',
action: function (dialog) {
defer.resolve(false);
dialog.close();
}
}],
close: function (dialog) {
dialog.remove();
}
});
return defer.promise();
}
function bsAlert(error, message) {
BootstrapDialog.show({
type: error ? BootstrapDialog.TYPE_DANGER : BootstrapDialog.TYPE_SUCCESS,
title: error ? "Error" : "Success",
message: message,
closeByBackdrop: false,
closeByKeyboard: false,
draggable: true,
buttons: [{
label: 'OK',
action: function (d) {
d.close();
}
}]
});
}
and using it (Pretty much the same way)
bsConfirm("Are you sure Bootstrap is what you wanted?").then(function (answer) {
if (answer) {
bsAlert("Well done! You have made the right choice");
} else {
bsAlert("I don't like you!");
}
});
