请帮忙,我是jquery的新手。有3个表格将填充文本框并下拉“选择”动态
<table class="primaGridViewSmall" border="0" cellpadding="0" width="95%"
id="shareAddUserMember" runat="server" clientidmode="Static" align="left">
</table>
<table class="primaGridViewSmall" border="0" cellpadding="0" width="95%"
id="shareAddUserMemberA" runat="server" clientidmode="Static" align="left">
</table>
<table class="primaGridViewSmall" border="0" cellpadding="0" width="95%"
id="shareAddUserMemberB" runat="server" clientidmode="Static" align="left">
</table>
该表可以有很多文本框和“选择”下拉,通过单击“添加更多”动态添加。 实际上我想从文本框中实现这样的东西并在该表中选择
var array = [];
var j = 0;
$('#shareAddUserMember tr').each(function () {
var memberID = ? // Dynamic_textbox_value;
var privilage = ? // Dynamic_drop_down_selected value ie type <select>
if (memberID != "") {
array[j] = memberID + ":" + privilage;
j++;
}
});
我试过这个来获取textbox的值,我还需要选择
$('#shareAddUserMember tr').each(function () {
$('input[type=text]').each(function (i, item) {
var grade = $(item).val();
alert(grade);
});
});
但是上面的代码将获取页面中的所有输入类型。我有多个表。我需要在表shareAddUserMember中动态创建的文本框中获取值(id是动态生成的。)
我只需要在id =“shareAddUserMember”而不是shareAddUserMemberA或shareAddUserMemberB的表中使用textbox的值。
$('#shareAddUserMember tr').each(function () {
// ---what to write here to fetch the textbox and drop down selected values-----------
});
实际上我想从文本框中实现这样的东西,并在该表中输入选择类型
var array = [];
var j = 0;
$('#shareAddUserMember tr').each(function () {
var memberID = ? // Dynamic_textbox_value;
var privilage = ? // Dynamic_drop_down_selected value ie type <select>
if (memberID != "") {
array[j] = memberID + ":" + privilage;
j++;
}
});
在tr中有下拉并选择样本DOM
<table class="primaGridViewSmall" border="0" cellpadding="0" width="95%"
id="shareAddUserMember" runat="server" clientidmode="Static" align="left">
<tr id="EmailIDUserRow1">
<td style="text-align: center; width: 3%;">
<input type="hidden" id="EmailUserMemberID1" name="EmailUserMemberID1" />
</td>
<td align="left">
<select style="width: 150px" name="select1" id="select1">
<option value="">Select</option>
<option value="1">Full Access </option>
<option value="0">View Only</option>
</select>
</td>
</tr>
</table>

迭代#shareAddUserMember
中的每个tr元素:
$("#shareAddUserMember tr").each(function() {
// `this` refers to the current tr element
// Get the input box and select that are inside the current tr element using
// $(this).find()
var memberID = $(this).find("input:text").val();
var privilege = $(this).find("select").val();
if (memberID !== "") {
// ...
}
});
希望有助于或至少指出正确的方向。

试试这段代码:
$('#shareAddUserMember tr input[type=text]').each(function () {
// do some of your magic in here :)
});
既然你已经更新了你的答案,你可以尝试这样的事情(我没有测试这段代码)
$('#shareAddUserMember').each(function () {
var memberID = $('#shareAddUserMember tr input[type=text]').val();
var privilage = $("#shareAddUserMember tr select option:selected").text();
if (memberID != "") {
array[j] = memberID + ":" + privilage;
j++;
}
});
