使用jQuery使用选择框选项值过滤JSON [英] Filter json with select box option value using jquery

问题描述

如何根据年份过滤制造"值.例如:当我选择年份"作为"2012"时，相关数据即；下拉框中仅应显示"def".另一个问题是，当我选择下一个值时，表中的上一个数据再次显示.请参阅该演示以获得更好的理解.

我尝试过了.

$ .each(g_Vehicle，function(index){
var sMake = g_Vehicle [index] .Make;
if($(''#DropDown_Year'').val())==''2011''){/*出于测试目的，我将年份指定为2011 */
if($ .inArray(sMake，g_MakesArray)== -1){
g_MakesArray.push(sMake);
}
}
});

How can i filter the "Make" values according to the year. For eg: When i select "Year" as "2012" the related data i.e; only "def" should be displayed in the drop down box. Another problem is the previous data in the table was shown again when i select next values. See the demo for better understanding.

I tried this.

$.each(g_Vehicle, function(index) {
var sMake = g_Vehicle[index].Make;
if($(''#DropDown_Year'').val())==''2011''){ /* for testing purpose i give year as 2011*/
if ($.inArray(sMake, g_MakesArray) == -1) {
g_MakesArray.push(sMake);
}
}
});

推荐答案

.each(g_Vehicle，function(index){
var sMake = g_Vehicle [index] .Make;
if(

.each(g_Vehicle, function(index) {
var sMake = g_Vehicle[index].Make;
if(

(''#DropDown_Year'').val())==''2011''){/*出于测试目的，我将年份设置为2011 */
if(

(''#DropDown_Year'').val())==''2011''){ /* for testing purpose i give year as 2011*/
if (

.inArray(sMake，g_MakesArray)== -1){
g_MakesArray.push(sMake);
}
}
});
