我正在使用JS从另一个选择列表的选项中动态填充选择列表。人口正常工作,但是一旦选择了第二个选项,我希望用户被导航到女孩URL。我错过了什么?
< script type = "text/javascript" >
function populate(s1, s2) {
var s1 = document.getElementById(s1);
var s2 = document.getElementById(s2);
s2.innerHTML = "";
if (s1.value == "Chevy") {
var optionArray = ["|", "http://www.example.com|Camaro", "http://www.example.com|Corvette", "impala|Impala"];
} else if (s1.value == "Dodge") {
var optionArray = ["|", "http://www.example.com|Avenger", "http://www.example.com|Challenger", "http://www.example.com|Charger"];
} else if (s1.value == "Ford") {
var optionArray = ["|", "http://www.example.com|Mustang", "http://www.example.com|Shelby"];
}
for (var option in optionArray) {
var pair = optionArray[option].split("|");
var newOption = document.createElement("option");
newOption.value = pair[0];
newOption.innerHTML = pair[1];
s2.options.add(newOption);
}
}
< /script>
<select id="slct1" name="slct1" onchange="populate(this.id,'slct2')">
<option value=""></option>
<option value="Chevy">Chevy</option>
<option value="Dodge">Dodge</option>
<option value="Ford">Ford</option>
</select>
<select id="slct2" name="slct2" onchange="form.submit()"></select>
答案 0 :(得分:1)
假设您的表单如下:
<form name='form' id='exampleForm' action='whatever'>...</form>
您的onchange
事件应如下所示:
onchange="document.form.submit()"
或
onchange="document.getElementById('exampleForm').submit()"
或者,您甚至不需要表格。你可以这样做:
onchange="window.location.href='my.url'"
......或者把它放在一个函数中:
onchange="foo()"
...
function foo() {
var s2 = document.getElementById('slct2');
window.location.href = "my.url?model=" + s2.options[s2.selectedIndex].value;
}
