问题更多的是调试/语法错误而非方法。
我在外部js文件中定义了一个函数(模态确认),它返回一个值:
function confirmation(question) {
var defer = $.Deferred();
$('<div></div>').html(question).dialog({
autoOpen: true,
modal: true,
title: 'Confirmation',
buttons: {
"Delete All Items": function() {
defer.resolve("true"); //this text 'true' can be anything. But for this usage, it should be true or false.
$(this).dialog("close");
},
"Cancel": function() {
defer.resolve("false"); //this text 'false' can be anything. But for this usage, it should be true or false.
$(this).dialog("close");
}
},
close: function() {
//$(this).remove();
$(this).dialog('destroy').remove()
}
});
}
现在当我尝试调用$(document).ready(function() {
内的函数时;我收到 未捕获参考错误 。
所有必需的文件都包含在调用脚本中。我想了解为什么这样以及如何解决这个问题?
答案 0 :(得分:0)
除了最后缺少的花括号,并假设你的&#34;必要文件&#34;包括jquery-ui,你的功能似乎没有任何问题。请参阅此jsfiddle,它不会产生任何错误。
也许问题出现在代码的其他地方?如果您可以发布Minimal, Complete, and Verifiable example。

});
function confirmation(question) {
var defer = $.Deferred();
$('<div></div>').html(question).dialog({
