问题描述
任何人都可以告诉我如何检查并将复选框选中的值添加到数组中?
在点击中获取选中的值并在javascript中存储在数组中。
这是我的代码。
function ajax(city)
{
var xmlhttp;
try {
xmlhttp = new XMLHttpRequest();
}
catch(e){
try {
xmlhttp = new ActiveXObject(Msxml2.XMLHTTP);
}
catch(e){
try {
xmlhttp = new ActiveXObject(Microsoft.XMLHTTP);
}
catch(e){
alert(你的浏览器不支持AJAX!);
返回false;
}
}
}
var url ='process.php?city ='+ city;
xmlhttp.onreadystatechange = function(){
if(xmlhttp.readyState == 4)
document.getElementById('search_city_projects')。innerHTML = xmlhttp.responseText;
}
xmlhttp.open(GET,url,true);
xmlhttp.send(null);
}
这是html代码..
< input type =checkboxname =checkbox []id =checkbox []value =<?php echo $ cities [$ i] - > city;?> onclick =ajax('<?php echo $ cities [$ i] - > city;?>'); />
我不知道如何添加从点击事件中获取的复选框值,然后存储这些值在一个数组中逐个数组,然后将这些数组的值传递给ajax调用。请帮助...
提前使用Thanx ...
你是说:
var chkedVals = new Array ; //存储已检查复选框的数组值
with(document.your_form_name){
for(var i = 0; i< checkbox.length; i ++){
if(checkbox [i] .checked){
chkedVals.push(checkbox [i] .value);
}
}
}
anyone can tell me how can i check and add checkbox checked values into an array?? get checked values on click and store in an array in javascript. This is my code.
function ajax(city)
{
var xmlhttp;
try {
xmlhttp=new XMLHttpRequest();
}
catch (e) {
try {
xmlhttp=new ActiveXObject("Msxml2.XMLHTTP");
}
catch (e) {
try {
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
catch (e) {
alert("Your browser does not support AJAX!");
return false;
}
}
}
var url='process.php?city='+city ;
xmlhttp.onreadystatechange=function() {
if(xmlhttp.readyState==4)
document.getElementById('search_city_projects').innerHTML = xmlhttp.responseText;
}

解决方案
Do you mean:
var chkedVals = new Array; //array to store checked checkboxes value
with(document.your_form_name) {
for(var i = 0; i < checkbox.length; i++){
if(checkbox[i].checked) {
chkedVals.push(checkbox[i].value);
}
}
}
