我是JavaScript新手，需要幫助來實現以下功能：當用戶輸入郵編時，表單中的任何其他條目都將被刪除，郵政編碼用於查找地址。如何在用戶輸入郵政編碼時清除表格？
我該怎麼做？以下是代碼由urgentcare領域我使用獲得位置附近：
(
function(){
var $scope, $location;
var urgentCareApp = angular.module('urgentCareApp',['ui.bootstrap']);
urgentCareApp.controller('UrgentCareController',function($scope,$http,$location,anchorSmoothScroll){
$scope.Lang = 'initVal';
$scope.ShowResults = false;
$scope.ShowDesc = true;
$scope.NoResults = false;
$scope.currentPage = 1;
$scope.maxPageNumbersToShow = 10;
$scope.formModel = {};
$scope.searchMode = 0;
$scope.miles = [{'value':'5'},{'value':'10'},{'value':'15'},{'value':'20' }];
$scope.searchParam = {};
$scope.searchParam.Distance = $scope.miles[0];
console.log($scope.searchParam.Distance);
//$scope.searchParam.Specialty = $scope.Specialties[0];
$scope.GetCurrentZip = function(){
try{
var lon, lat;
console.log('starting geoposition code.');
if("geolocation" in navigator){
window.navigator.geolocation.getCurrentPosition(function(pos){
lat = pos.coords.latitude.toFixed(3);
lon = pos.coords.longitude.toFixed(3);
console.log(lat + ' ' + lon);
$http.get("/remote/ReturnCurrentZipcode.cfm?Lat=" + lat + "&Lon=" + lon)
.success(function(response){
console.log('Response: ' + response);
$scope.searchParam.Zip = response;
console.log('object set');
})
})
}
else{ console.log('No geolocation'); }
}
catch(err) { console.log(err.message); }
}
$scope.GetCityList = function(){
try{
$http.get("/remote/ReturnUrgentCareCityList.cfm")
.success(function(response){
$scope.Cities = response.Cities;
})
}
catch(err){}
}
$scope.SearchUrgentCare = function(searchParam){
try{
$scope.searchMode = 1;
var queryString='';
if($scope.formModel && $scope.formModel !== searchParam){
$scope.resultsCount = 0;
currentPage = 1;
}
if(searchParam){
$scope.formModel = searchParam;
for(var param in searchParam){
console.log(param + ' ' + searchParam.hasOwnProperty(param) + ' ' + searchParam[param]);
if(searchParam.hasOwnProperty(param)){
var paramValue = searchParam[param].value ? searchParam[param].value.trim() : searchParam[param].trim();
if (paramValue.length > 0)
queryString += param + '=' + paramValue + '&';
}
}
}
console.log(queryString);
queryString= '?' + queryString + 'currentpage=' + $scope.currentPage;
$http.get("/remote/ReturnUrgentCareList.cfm" + queryString)
.success(function(response){
$scope.urgentCareCenters = response.UrgentCareCenters;
$scope.resultsCount = response.rowCount;
if (!$scope.urgentCareCenters){
$scope.NoResults = true;
$scope.ShowResults = false;
$scope.ShowDesc = false;
}
else{
$scope.NoResults = false;
$scope.ShowResults = true;
$scope.ShowDesc = false;
}
})
}
catch(err){ alert('No response.: ' + err.message); }
}
$scope.$watchGroup(['currentPage'], function(){
try{
if($scope.searchMode == 1){
$scope.SearchUrgentCare($scope.formModel);
}
}
catch(err){}
});
$scope.GetCityList();
$scope.GetCurrentZip();
$scope.gotoElement = function (eID){
var browserWidth = screen.availWidth;
if (browserWidth < 768)
anchorSmoothScroll.scrollTo(eID);
};
});
urgentCareApp.service('anchorSmoothScroll', function(){
this.scrollTo = function(eID) {
// This scrolling function
// is from http://www.itnewb.com/tutorial/Creating-the-Smooth-Scroll-Effect-with-JavaScript
var startY = currentYPosition();
var stopY = elmYPosition(eID);
var distance = stopY > startY ? stopY - startY : startY - stopY;
if (distance < 100) {
scrollTo(0, stopY); return;
}
var speed = Math.round(distance/100);
if (speed >= 20) speed = 20;
var step = Math.round(distance/25);
var leapY = stopY > startY ? startY + step : startY - step;
var timer = 0;
if (stopY > startY) {
for (var i=startY; i<stopY; i+=step) {
setTimeout("window.scrollTo(0, "+leapY+")", timer * speed);
leapY += step; if (leapY > stopY) leapY = stopY; timer++;
} return;
}
for (var i=startY; i>stopY; i-=step) {
setTimeout("window.scrollTo(0, "+leapY+")", timer * speed);
leapY -= step; if (leapY < stopY) leapY = stopY; timer++;
}
function currentYPosition() {
// Firefox, Chrome, Opera, Safari
if (self.pageYOffset) return self.pageYOffset;
// Internet Explorer 6 - standards mode
if (document.documentElement && document.documentElement.scrollTop)
return document.documentElement.scrollTop;
// Internet Explorer 6, 7 and 8
if (document.body.scrollTop) return document.body.scrollTop;
return 0;
}
function elmYPosition(eID) {
var elm = document.getElementById(eID);
var y = elm.offsetTop;
var node = elm;
while (node.offsetParent && node.offsetParent != document.body) {
node = node.offsetParent;
y += node.offsetTop;
} return y;
}
};
});
urgentCareApp.directive('allowPattern',[allowPatternDirective]);
function allowPatternDirective(){
return{
restrict: "A",
compile: function(tElement, tAttrs){
return function(scope, element, attrs){
element.bind("keypress", function(event){
var keyCode = event.which || event.keyCode;
var keyCodeChar = String.fromCharCode(keyCode);
if(!keyCodeChar.match(new RegExp(attrs.allowPattern, "i"))){
event.preventDefault();
return false;
}
});
}
}
}
}
urgentCareApp.filter('PhoneNumber', function(){
return function(phoneNumber){
var dash = '-';
if(phoneNumber){
var pn = phoneNumber;
pn = [pn.slice(0, 6), dash, pn.slice(6)].join('');
pn = [pn.slice(0, 3), dash, pn.slice(3)].join('');
return pn;
}
return phoneNumber;
}
});
})();
的形式爲：
<div class="panel panel-default">
<div class="panel-body">
<form name="UrgentCareSearch" ng-submit="SearchUrgentCare(searchParam);" novalidate="" role="form">
<div class="form-group"><input class="form-control" id="urgentcare" ng-model="searchParam.UrgentCareName" placeholder="Urgent Care Name" type="text" /></div>
<div class="form-group"><select class="form-control" id="city" ng-model="searchParam.City" ng-options="City.value for City in Cities"><option disabled="disabled" selected="selected" value="">City</option> </select></div>
<hr />
<div style="margin-top:-10px; margin-bottom:10px; text-align:center; font-size:8pt! important">* or Search by Zip code radius *</div>
<div class="row">
<div class="col-xs-7 no-right-padding">
<div class="form-group">
<div class="input-group"><select class="form-control" name="distance" ng-model="searchParam.Distance" ng-options="mile.value for mile in miles"></select>
<div class="input-group-addon">miles</div>
</div>
</div>
</div>
<div class="col-xs-5 no-left-padding">
<div class="form-group"><input allow-pattern="[\d\W]" class="form-control" id="zip" maxlength="5" ng-model="searchParam.Zip" placeholder="Zip code" type="text" /></div>
</div>
</div>
<div class="form-group"><input class="btn btn-warning btn-block" ng-click="gotoElement('SearchResultsAnchor');" type="submit" value="Search" /></div>
</form>
</div>
</div>
哪裏是你的形式？.. – developer033
剛剛添加的形式 –
我想清除所有字段如果用戶有輸入一個郵政編碼。當發生這種情況時，它應該顯示附近的位置 –
