我之前已经回答过:Javascript: Move caret to last character

jsFiddle:http://jsfiddle.net/ghAB9/6/

代码:

<textarea id="test">Some text</textarea>

function moveCaretToEnd(el) {
    if (typeof el.selectionStart == "number") {
        el.selectionStart = el.selectionEnd = el.value.length;
    } else if (typeof el.createTextRange != "undefined") {
        el.focus();
        var range = el.createTextRange();
        range.collapse(false);
        range.select();
    }
}

var textarea = document.getElementById("test");

textarea.onfocus = function() {
    moveCaretToEnd(textarea);

    // Work around Chrome's little problem
    window.setTimeout(function() {
        moveCaretToEnd(textarea);
    }, 1);
};
