JQuery:动态创建选择标记

Question

我正在使用JQuery动态(基于用户选择)创建标记.用户在文本框中输入require选项,我的代码创建了它的select标签.脚本是:

var numbersString = "1,2,3,4,5,6";
var data = numbersString.split(',');

var s = $("<select id=\"selectId\" name=\"selectName\" />");
for(var val in data) {
    $("<option />", {value: val, text: data[val]}).appendTo(s);
}
s.appendTo("#msj_form");

其中msj_form是标签附加的div id.现在它创建:

<select id="selectId" anme="selectName">
    <option value="0">1</option>
    <option value="1">2</option>
    <option value="2">3</option>
    <option value="3">4</option>
    <option value="4">5</option>
    <option value="5">6</option>
</select>

但我也希望将标签和<tr><td>代码与标签结合起来,使代码看起来像:

<tr>
    <td>My Label</td>
    <td>
        <select id="selectId" anme="selectName">
            <option value="0">1</option>
            <option value="1">2</option>
            <option value="2">3</option>
            <option value="3">4</option>
            <option value="4">5</option>
            <option value="5">6</option>
        </select>
    </td>
</tr>

Answer 1

var s = $("<select id=\"selectId\" name=\"selectName\" />");
for(var val in data) {
    $("<option />", {value: val, text: data[val]}).appendTo(s);
}

在for循环之后,用TableRow和Cells包装所有内容,像这样,Jquery Wrap()

$(s).wrap('<table><tr><td></td></tr></table>');

<!-- Create Dropdown -->
/* 1- First get total numbers of SELECT tags used in your page to avoid elements name/id issues.
 * 2- Get all OPTIONS user entered with comma separator into a text box.
 * 3- Split user OPTIONS and make an array of these OPTIONS.
 * 4- Create SELECT code.
 * 5- Appent it into the temp div (a hidden div in your page).
 * 6- Then get that code.
 * 7- Now append code to your actual div.
 * 8- Filnally make empty the temp div therfore it will be like a new container for next SELECT tag.
 */

total = $("select").size() + 1;                                         // 1-
var myoptions = $("#myoptions").val();                                  // 2-
var data = myoptions.split(',');                                        // 3-
var s = $("<select id=\""+total+"\" name=\""+total+"\" />");            // 4-
for(var val in data) {
    $("<option />", {value: val, text: data[val]}).appendTo(s);
}
s.appendTo("#tempselect");                                              // 5-
var getselectcode = $("#tempselect").html();                            // 6-
$("#msj_form").append(appendLabel+"<td>"+getselectcode+"</td></tr>");   // 7-
$("#tempselect").html('');                                              // 8-

<div style="display:none;" id="tempselect"></div>                       // Temp div
