每当我在下面的插入超链接文本输入中键入内容时,所有单词都将转到后面的textarea.确定和取消按钮工作正常,但我不能专注于文本输入.
我们正在使用jQuery UI 1.10.1.它与之前版本的jQuery(1.8.x)运行良好.
我已经检查了jQuery背后的代码,并且在打开模态对话框时调用了以下方法：
_focusTabbable: function () {
// Set focus to the first match:
// 1. First element inside the dialog matching [autofocus]
// 2. Tabbable element inside the content element
// 3. Tabbable element inside the buttonpane
// 4. The close button
// 5. The dialog itself
var hasFocus = this.element.find("[autofocus]");
if (!hasFocus.length) {
hasFocus = this.element.find(":tabbable");
}
if (!hasFocus.length) {
hasFocus = this.uiDialogButtonPane.find(":tabbable");
}
if (!hasFocus.length) {
hasFocus = this.uiDialogTitlebarClose.filter(":tabbable");
}
if (!hasFocus.length) {
hasFocus = this.uiDialog;
}
hasFocus.eq(0).focus();
},_keepFocus: function (event) {
function checkFocus() {
var activeElement = this.document[0].activeElement,isActive = this.uiDialog[0] === activeElement ||
$.contains(this.uiDialog[0],activeElement);
if (!isActive) {
this._focusTabbable();
}
}
event.preventDefault();
checkFocus.call(this);
// support: IE
// IE <= 8 doesn't prevent moving focus even with event.preventDefault()
// so we check again later
this._delay(checkFocus);
},
解决方法
第二个答案我发现在下面的代码中jQuery将文档绑定到对话框.因此,当我点击所需按钮的onclick事件(或您正在处理的任何事件)时解除绑定：
if (window.jQuery && window.jQuery.ui.dialog) {
$(document).unbind("focusin.dialog");
}
这是jQuery UI将_focusTabble()方法绑定到focusin.dialog事件的文件.
if ( !$.ui.dialog.overlayInstances ) {
// Prevent use of anchors and inputs.
// We use a delay in case the overlay is created from an
// event that we're going to be cancelling. (#2804)
this._delay(function() {
// Handle .dialog().dialog("close") (#4065)
if ( $.ui.dialog.overlayInstances ) {
this.document.bind( "focusin.dialog",function( event ) {
if ( !$( event.target ).closest(".ui-dialog").length &&
// TODO: Remove hack when datepicker implements
// the .ui-front logic (#8989)
!$( event.target ).closest(".ui-datepicker").length ) {
event.preventDefault();
$(".ui-dialog:visible:last .ui-dialog-content")
.data("ui-dialog")._focusTabbable();
}
});
}
});
}
