先扫下盲:tipswindown是jQuery的弹窗插件,可以使用url或当前页元素显示在模拟层中;hintbox是jQuery的类似Google Suggestions插件。
使用情形如下:
页面a.aspx中点击按钮弹出模拟层,在这个层中有一个输入文本框“监督人”处调用hintbox来产生即时查询功能。
直接调用产生了如下情形:
于是找到jquery.hintbox-1.3.js这个文件,发现其中出现这么一行:
$(
"
#windown-content
"
).ajaxStart(
function
(){
$( this ).html( " <img src=' " + templateSrc + " /images/loading.gif' class='loading' /> " );
});
$( this ).html( " <img src=' " + templateSrc + " /images/loading.gif' class='loading' /> " );
});
将其改为:
$(
"
#windown-content
"
).html(
"
<img src='
"
+
templateSrc
+
"
/images/loading.gif' class='loading' />
"
);
原因是两个插件即使是在不同情形下触发ajax事件,使用的仍是同一对象,即jQuery.js中出现的


ajaxSetup:
function
( settings ) {
jQuery.extend( jQuery.ajaxSettings, settings );
},
ajaxSettings: {
url: location.href,
global: true ,
type: " GET " ,
contentType: " application/x-www-form-urlencoded " ,
processData: true ,
async: true ,
/*
timeout: 0,
data: null,
username: null,
password: null,
*/
// Create the request object; Microsoft failed to properly
// implement the XMLHttpRequest in IE7, so we use the ActiveXObject when it is available
// This function can be overriden by calling jQuery.ajaxSetup
xhr: function (){
return window.ActiveXObject ? new ActiveXObject( " Microsoft.XMLHTTP " ) : new XMLHttpRequest();
},
accepts: {
xml: " application/xml, text/xml " ,
html: " text/html " ,
script: " text/javascript, application/javascript " ,
json: " application/json, text/javascript " ,
text: " text/plain " ,
_default: " */* "
}
},
jQuery.extend( jQuery.ajaxSettings, settings );
},
ajaxSettings: {
url: location.href,
global: true ,
type: " GET " ,
contentType: " application/x-www-form-urlencoded " ,
processData: true ,
async: true ,
/*
timeout: 0,
data: null,
username: null,
password: null,
*/
// Create the request object; Microsoft failed to properly
// implement the XMLHttpRequest in IE7, so we use the ActiveXObject when it is available
// This function can be overriden by calling jQuery.ajaxSetup
xhr: function (){
return window.ActiveXObject ? new ActiveXObject( " Microsoft.XMLHTTP " ) : new XMLHttpRequest();
},
accepts: {
xml: " application/xml, text/xml " ,
html: " text/html " ,
script: " text/javascript, application/javascript " ,
json: " application/json, text/javascript " ,
text: " text/plain " ,
_default: " */* "
}
},
这样在当前窗体中就会是只有一个xhr对象存在,因为在hintbox中的ajax事件会触发tipswindown的ajaxStart事件。
