<input type="text" id="one" onkeyup="suggest(event,this)" />
<p>
<input type="text" id="two" onkeyup="suggest(event,this)" />
<p>
<input type="text" id="two" onkeyup="suggest(event,this)" />

javascript:
function suggest(e,the)
{
    //here i want to create a div and place just below the textbox on which the keyispressed
}

any help!

一般来说，将 javascript 事件附加到 html 中并不是一个好主意。我的想法是动态创建一个 div 并将其放置在输入字段的正下方，我认为以下代码将起作用。这里也是一个 jsfiddle http://jsfiddle.net/krasimir/qCXPu/3/

<div class="wrapper">
<input type="text" id="one" class="suggest" />
<p>some text</p>
<input type="text" id="two" class="suggest" />
<p>some text</p>
<input type="text" id="three" class="suggest" />
</div>

JavaScript：

var inputs = document.querySelectorAll('.suggest');
for(var i=0; field=inputs[i]; i++) {
    field.addEventListener('keyup', function(event) {
        var text = 'You typed: ' + this.value;

        if(!this.suggestion) {
            var rect = this.getBoundingClientRect();
            var left = rect.left;
            var top = rect.bottom;
            this.suggestion = document.createElement('DIV');            
            this.suggestion.innerHTML = text;
            this.suggestion.setAttribute('style', 'background: #B0B0B0; padding: 6px; position: absolute; top: ' + top + 'px; left: ' + left + 'px;');
            this.parentNode.appendChild(this.suggestion);
        } else {
            this.suggestion.innerHTML = text;
            this.suggestion.style.display = 'block';
        }        

    });
    field.addEventListener('blur', function(event) {
        if(this.suggestion) {
            this.suggestion.style.display = 'none';
        }
    });
}

尝试这个 ：

    <input type="text" id="one" onkeyup="suggest(this)" />
    <p>
    <input type="text" id="two" onkeyup="suggest(this)" />
    <p>
    <input type="text" id="two" onkeyup="suggest(this)" />

javascript：

function suggest(obj)
    {
        $('<div><p>inserted div</p><div>').insertAfter(obj);
    }

尝试这个

function suggest(e,the)
{
    $(e).after($("#div").show('slow'));
}

或这个

function suggest(e,the)
{
    $(the).after($("#div").show('slow'));
}

利用

function suggest(e,the) { $(the).after("<div>Some content</div>"); }

我在这里创建了示例。这将用于在文本框下方添加 div。

更完美的代码在这里

#bottom-div {
    z-index: 999;
    position: absolute;
    min-width: 290px;
    background: #fff;
    padding: 10px;
    border: 1px solid #ccc;
    height: 80px;
    cursor: pointer;
    display: none;
    border-top-color: #000;
}

    #bottom-div > div {
        padding-bottom: 5px;
    }
