我遇到了Jquery函数的问题。
我从谷歌获得了jquery库。
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.1/jquery-ui.min.js"></script>
首先,我将以下代码放在.js
上(function($){
jQuery.fn.jConfirmAction = function (options) {
var theOptions = jQuery.extend ({
question: "Are You Sure ?",
yesAnswer: "Yes",
cancelAnswer: "Cancel"
}, options);
return this.each (function () {
$(this).bind('click', function(e) {
var submitBtn = $(this);
if($(this).attr("jconfirmed")){
submitBtn.removeAttr("jconfirmed");
}else{
e.preventDefault();
thisHref = $(this).attr('href');
var btns = {};
btns[theOptions.yesAnswer]=function() {
$( this ).dialog( "close" );
if (thisHref!=null){
window.location = thisHref;
}else{
submitBtn.attr("jconfirmed", true);
submitBtn.click();
}
};
btns[theOptions.cancelAnswer]=function() {
$( this ).dialog( "close" );
submitBtn.removeAttr("jconfirmed");
};
var content='<p>'+theOptions.question+'</p>';
if(theOptions.checkboxText!=undefined){
content='<p>'+'<input type="checkbox" id="cbox">'+theOptions.checkboxText+'<br/><br/>'+theOptions.question+'</p>';
}
$('#dialog-confirm').html(content);
$('#cbox').click(function() {
/*
if($('#cbox').attr("checked")){
$('.ui-dialog-buttonset button:first-child').show();
}else{
$('.ui-dialog-buttonset button:first-child').hide();
}
*/
});
$('#dialog-confirm').dialog({
resizable: false,
modal: true,
buttons: btns,
show: {
effect: "blind",
duration: 1000
},
hide: {
effect: "explode",
duration: 1000
},
draggable: false,
dialogClass: 'main-dialog-class'
});
}
});
});
};
})(jQuery);
并且,在jsp文件中调用函数。
<script type="text/javascript">
$(document).ready(function() {
$('.confirm').jConfirmAction();
});
</script>
但我在控制台中出现以下错误:
Uncaught TypeError:Object [object Object]没有方法'jConfirmAction'
我尝试通过将函数代码放在<script type="text/javascript"></script>
之间的同一个jsp中来解决这个问题。这适用于某些页面,但在其他页面中具有相同的错误。有没有办法只在加载了jquery时调用该函数?
答案 0 :(得分:1)
使用document.ready()
包装整个JS代码$(document).ready(function () {
(function ($) {
jQuery.fn.jConfirmAction = function (options) {
var theOptions = jQuery.extend({
question: "Are You Sure ?",
yesAnswer: "Yes",
cancelAnswer: "Cancel"
}, options);
return this.each(function () {
$(this).bind('click', function (e) {
var submitBtn = $(this);
if ($(this).attr("jconfirmed")) {
submitBtn.removeAttr("jconfirmed");
} else {
e.preventDefault();
thisHref = $(this).attr('href');
var btns = {};
btns[theOptions.yesAnswer] = function () {
$(this).dialog("close");
if (thisHref !== null) {
window.location = thisHref;
} else {
submitBtn.attr("jconfirmed", true);
submitBtn.click();
}
};
btns[theOptions.cancelAnswer] = function () {
$(this).dialog("close");
submitBtn.removeAttr("jconfirmed");
};
var content = '<p>' + theOptions.question + '</p>';
if (theOptions.checkboxText !== undefined) {
content = '<p>' + '<input type="checkbox" id="cbox">' + theOptions.checkboxText + '<br/><br/>' + theOptions.question + '</p>';
}
$('#dialog-confirm').html(content);
$('#cbox').click(function () {
/*
if($('#cbox').attr("checked")){
$('.ui-dialog-buttonset button:first-child').show();
}else{
$('.ui-dialog-buttonset button:first-child').hide();
}
*/
});
$('#dialog-confirm').dialog({
resizable: false,
modal: true,
buttons: btns,
show: {
effect: "blind",
duration: 1000
},
hide: {
effect: "explode",
duration: 1000
},
draggable: false,
dialogClass: 'main-dialog-class'
});
}
});
});
};
})(jQuery);
});
在文件末尾包含所有JS文件,然后重试,并注意一下?使用'!=='将变量与'null'和'undefined'进行比较
