我不会通过链接onclick与jquery将HTML插入到ace编辑器中。就我成功而言,即使在尝试这个脚本时也是如此:

使用Javascript:

function insertAtCaret(areaId,text) {
    var txtarea = document.getElementById(areaId);
    var scrollPos = txtarea.scrollTop;
    var strPos = 0;
    var br = ((txtarea.selectionStart || txtarea.selectionStart == '0') ? 
        "ff" : (document.selection ? "ie" : false ) );
    if (br == "ie") { 
        txtarea.focus();
        var range = document.selection.createRange();
        range.moveStart ('character', -txtarea.value.length);
        strPos = range.text.length;
    }
    else if (br == "ff") strPos = txtarea.selectionStart;

    var front = (txtarea.value).substring(0,strPos);  
    var back = (txtarea.value).substring(strPos,txtarea.value.length); 
    txtarea.value=front+text+back;
    strPos = strPos + text.length;
    if (br == "ie") { 
        txtarea.focus();
        var range = document.selection.createRange();
        range.moveStart ('character', -txtarea.value.length);
        range.moveStart ('character', strPos);
        range.moveEnd ('character', 0);
        range.select();
    }
    else if (br == "ff") {
        txtarea.selectionStart = strPos;
        txtarea.selectionEnd = strPos;
        txtarea.focus();
    }
    txtarea.scrollTop = scrollPos;
}

HTML链接:

<a href="#" onclick="insertAtCaret('ace_text-input','<h1></h1>');return false;">Click Here to Insert</a>

尝试实现类似于WYSIWYG编辑器的效果,只在编辑器中显示原始HTML。
