获取选择框的正确结果时出现问题 [英] Problem in getting right result for select box
问题描述
我正在使用Jquery：
i am using Jquery as:
$(document).ready(function(){
test("price");
alert("hi");
$("#item2").change(function()
{
sort= $("#item2").val();
test(sort);
});
});
函数test（）是一些javascript函数，我的问题是当页面按价格加载函数调用时参数。当我从选择框中选择一些项时，使用sort参数调用test（）（通过警告框验证）。但我没有得到正确的结果。我的意思是当我从选择框中选择选项时，我的test（）结果与price一样，我认为这可能是问题因为Jquery的 $（文档）.ready（function（） { ,. test（）函数根据参数制作一些html代码并在网页上显示
请建议我可以解决的问题
function test() is some javascript function, my problem is when page loads function calls by "price" parameter .Now when i select some item from select box function test() is called using sort parameter (verify by alert box). but i am not getting the correct result. i mean when i select option from select box than also my result of test() is as with "price" , i suppose it might be the problem because of Jquery's $(document).ready(function(){,. test() function make some html code based on the parameter and show it on the web page
Please suggest me what can be the solution
编辑：
功能测试（）是：
function test(sort)
