Javascript 基于锚定值的动态表单输入

我有以下打开单个模式表单的代码段：

<a class="modalbox" id="foo" href="#inline">Request a Quote</a>
<a class="modalbox" id="bar" href="#inline">Request a Quote</a>
...and so on...

我建议使用纯JavaScript，类似于：

function addTextToInput(from, to, prefix, e) {
    e = e || window.event;
    if (!from || !to) {
        return false;
    }
    else {
        from = from.nodeType == 1 ? from : document.getElementById(from);
        to = to.nodeType == 1 ? to : document.getElementById(to);
        var text = from.id;
        to.value = prefix ? prefix + ' ' + text : text;
    }
}

var as = document.querySelectorAll('a.modalbox');
for (var i = 0, len = as.length; i<len; i++) {
    as[i].onclick = function(e) {
        addTextToInput(this, 'sub', 'I am interested in', e);
    };
}​

Perfect-您发布的JQuery解决方案立即生效。非常感谢。（另外，我有点沾沾自喜的是，简单的JS版本也能工作！=D）

$('a').click(function(e) {

 $('#product').val($(this).attr('id'));

function addTextToInput(from, to, prefix, e) {
    e = e || window.event;
    if (!from || !to) {
        return false;
    }
    else {
        from = from.nodeType == 1 ? from : document.getElementById(from);
        to = to.nodeType == 1 ? to : document.getElementById(to);
        var text = from.id;
        to.value = prefix ? prefix + ' ' + text : text;
    }
}

var as = document.querySelectorAll('a.modalbox');
for (var i = 0, len = as.length; i<len; i++) {
    as[i].onclick = function(e) {
        addTextToInput(this, 'sub', 'I am interested in', e);
    };
}​

$('a.modalbox').click(function(e){
    e.preventDefault();
    $('#sub').val('I am interested in ' + this.id);
});
