我有一个selectlist,它是在网格中使用jquery构建的。当用户输入一个键构建选择列表时,我然后调用click()和focus(),以便我可以再次使用键命令。
我遇到的问题是.focus()在触发时会触发选择列表的选择。有没有人以前经历过这种行为或找到了解决方法?提前致谢
function INTEREST_createPaymentTypeDropDown() {
//Interest specific:
//build a dropdown for the enum
//if the PaymentType input exists
if ($("#PaymentType").length > 0) {
var cellPaymentTypeValue = $("#PaymentType").val();
var selectedOption;
$("#PaymentType").replaceWith("<select id='PaymentType' style='width:95px; height: 20px;' name='PaymentType'></select>");
$.each(INTEREST_PAYMENT_TYPES, function(key, val) {
var newoption = $("<option value=\"" + val + "\">" + key + "</option>");
if (val == cellPaymentTypeValue || key == cellPaymentTypeValue) {
//append select to the current value
selectedOption = val;
}
$("#PaymentType").append(newoption);
$("#PaymentType").addClass("t-input");

$("#PaymentType").val(selectedOption.toString());

答案 0 :(得分:0)
可能是列表顶部没有空选项,以便在调用click()
时导致PaymentType
自动选择第0个选项吗?
