我无法获取动态复选框的选中值.我究竟做错了什么？http://jsfiddle.net/hxfsB/17/
标记:
<html>
<body>
one<input type="checkbox" name='checkbox0' value="one_name" checked>
two<input type="checkbox" name='checkbox1' value="one_name1">
three<input type="checkbox" name='checkbox2' value="one_name2">
<input type="button" id="envoyer" value="Envoyer Reponse" />
</body>
</html>
使用Javascript:
$('#envoyer').click(function(e){
var myArray=new Array(4);
for ( var j = 0; j < 3; j++){
var check=$('input:checkbox[name=checkbox'+j+']').is(':checked');
if(check==true)
myArray[j]=$('input:checkbox[name=checkbox'+j+']').val();
}
alert('check '+" "+myArray[i]);
});
尝试使用java脚本将选择查询的结果存储到数组时,我遇到了问题.问题是在函数内部,数组包含正确的值但在它之外是空的,即使我使用全局变量它仍然是空的!
db.transaction(function (transaction) {
var sql = "SELECT * FROM Question where idEnq=" + idEn;
transaction.executeSql(sql, undefined, function (transaction, result) {
var res = document.getElementById('results');
res.innerHTML = "<ul>";
if (result.rows.length) {
for (var i = 0; i < result.rows.length; i++) {
var row = result.rows.item(i);
ch[i] = new qu(row.id, row.text, row.type);
res.innerHTML += '<li>' + row.id + ' ' + ch[i].text + ' ' + ch[i].type + '</li>';
}
tablo = ch;
} else {
alert("No choices");
res.innerHTML += "<li> No choices …我想用动态值填充我的下拉列表,但列表仍然为空,换句话说没有显示选项有人可以帮助我!!! 这是我的代码http://jsfiddle.net/n6ahz/24/
var newdiv = document.createElement('div');
var text="TEXT";
var n=0;
newdiv.innerHTML += "<br> Question " + (n) + " : " + text + " ? <br><br>";
var m = 0;
var options = '';
for (var j = 1; j < 5; j++) {
var val = "marwa" + j;
if (val) {
m++;
options += " <option value="+j+"> " + val + "</option>";
}
}
newdiv.innerHTML += "<select name='single' id='single'>";
newdiv.innerHTML += " "+options + " </select> …
