我无法理解 jQuery UI 选项卡教程的某个部分。特别是这部分#{href}'>#{label}
它在做什么/它是什么意思?
完整代码:
$(function () {
var tabTitle = $("#tab_title"),
tabContent = $("#tab_content"),
tabTemplate = "<li><a href='#{href}'>#{label}</a> <span class='ui-icon ui-icon-close' role='presentation'>Remove Tab</span></li>",
tabCounter = 3;
var tabs = $("#tabs").tabs();
// modal dialog init: custom buttons and a "close" callback reseting the form inside
var dialog = $("#dialog").dialog({
autoOpen: false,
modal: true,
buttons: {
Add: function () {
addTab();
$(this).dialog("close");
},
Cancel: function () {
$(this).dialog("close");
}
},
close: function () {
form[0].reset();
}
});
// addTab form: calls addTab function on submit and closes the dialog
var form = dialog.find("form").submit(function (event) {
addTab();
dialog.dialog("close");
event.preventDefault();
});
// actual addTab function: adds new tab using the input from the form above
function addTab() {
var label = tabTitle.val() || "Tab " + tabCounter,
id = "tabs-" + tabCounter,
li = $(tabTemplate.replace(/#\{href\}/g, "#" + id).replace(/#\{label\}/g, label)),
tabContentHtml = tabContent.val() || "Tab " + tabCounter + " content.";
tabs.find(".ui-tabs-nav").append(li);
tabs.append("<div id='" + id + "'><p>" + tabContentHtml + "</p></div>");
tabs.tabs("refresh");
tabCounter++;
}
// addTab button: just opens the dialog
$("#add_tab")
.button()
.click(function () {
dialog.dialog("open");
});
// close icon: removing the tab on click
tabs.delegate("span.ui-icon-close", "click", function () {
var panelId = $(this).closest("li").remove().attr("aria-controls");
$("#" + panelId).remove();
tabs.tabs("refresh");
});
tabs.bind("keyup", function (event) {
if (event.altKey && event.keyCode === $.ui.keyCode.BACKSPACE) {
var panelId = tabs.find(".ui-tabs-active").remove().attr("aria-controls");
$("#" + panelId).remove();
tabs.tabs("refresh");
}
});
});
