更新javascript全局变量 [英] Updating javascript global variable
问题描述
我在asp.net开发工作,我有两个文件,即
i)UserControl
ii).js(javascript)
在.js文件中以下是代码
I am working in asp.net development, I have Two files i.e.
i) UserControl
ii).js (javascript)
In .js File following is code
var varBindNewSalesTranGrid = '';
function BindNewSalesAttribute() {
$.ajax({
type: "POST",
url: "/url of Webmthod returns string",
data: '{}',
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (data) {
varBindNewSalesTranGrid += data.d;
},
error: function (xhr, ajaxOptions, thrownError) {
}
});
}
在Usercontrol文件中
In Usercontrol file
$(document).ready(function () {
BindNewSalesAttribute();
alert(varBindNewSalesTranGrid);
});
//Which is file referenced above .js file
当我运行我的usercontrol文件时,我看到varBindNewSalesTranGrid的值为空('').Function返回值'TestString',我在BindNewSalesAttribute函数中赋值varBindNewSalesTranGrid但仍然没有更新值。
如果您有任何想法,请告诉我。
When I run my usercontrol file I see the value of varBindNewSalesTranGrid is empty ('').Function returns value 'TestString' and I am assigning value varBindNewSalesTranGrid in BindNewSalesAttribute function but still value is not getting updated.
if you have any ideas then let me know.

},
错误:函数(xhr,ajaxOptions ,thrownError){
}
});
}
.ajax({ type: "POST", url: "/url of Webmthod returns string", data: '{}', contentType: "application/json; charset=utf-8", dataType: "json", success: function (data) { varBindNewSalesTranGrid += data.d; }, error: function (xhr, ajaxOptions, thrownError) { } }); }

alert(varBindNewSalesTranGrid);
});
//哪个是上面引用的文件.js文件
(document).ready(function () { BindNewSalesAttribute(); alert(varBindNewSalesTranGrid); }); //Which is file referenced above .js file
