我正在研究一個Web應用程序,要求用戶輸入並根據其選擇返回信息。我有兩個要求國家和州的複選框。當這兩個條件都滿足時,提交按鈕應該返回基於國家和州的信息。使用HTML中的提交按鈕返回信息
我的問題是,我如何使提交按鈕獲取輸入的信息並將其轉換爲下一頁上的數據(結果)?我有一個search.html和一個search_results.html。我需要一個search.html還是可以根據輸入信息從selectCountry.html轉到search_results.html?
我正在使用HTML,angularJs和Javascript。爲了更好地理解我的問題,我的鏈接是http://travel-buddy.us/selectCountry.html,[提交按鈕不做任何事情]。

var selectedCountryIndex = document.getElementById(countryElementId).selectedIndex;
var stateElement = document.getElementById(stateElementId);
stateElement.length=0;
stateElement.options[0] = new Option('Select State','');
stateElement.selectedIndex = 0;
var state_arr = s_a[selectedCountryIndex].split("|");
for (var i=0; i<state_arr.length; i++) {
stateElement.options[stateElement.length] = new Option(state_arr[i],state_arr[i]);
}
}
function populateCountries(countryElementId, stateElementId){
// given the id of the <select> tag as function argument, it inserts <option> tags
var countryElement = document.getElementById(countryElementId);
countryElement.length=0;
countryElement.options[0] = new Option('Select Country','-1');
countryElement.selectedIndex = 0;
for (var i=0; i<country_arr.length; i++) {
countryElement.options[countryElement.length] = new Option(country_arr[i],country_arr[i]);
}
// Assigned all countries. Now assign event listener for the states.
if(stateElementId){
countryElement.onchange = function(){
populateStates(countryElementId, stateElementId);
};
}

您正在使用angular.I不理解您爲什麼需要頁面刷新? –
