我正在搞乱一些jQuery,并通过构建my own version的Github Pages tutorial来教自己一些基础知识。我发现为了在不同的地方实现类似的功能,我倾向于重复我的功能。
// USER / ORGANISATION SITE
// ----------------------- //
// User clicks on #userSite
$("#js-userSite").click( function() {
// Check if body has other class, if so remove it
if( $("body").hasClass("showProjectSite") ) {
$("body").removeClass("showProjectSite");
}
// And an appropriate class is added to the body
$("body").addClass("showUserSite");
});
// USER / ORGANISATION SITE ----> CHOOSE GIT CLIENT
// ----------------------------------------------- //
// Click event
$("#js-gitClientTerminal").click( function() {
// Check if body has other classes, if so remove it
if( $("body").hasClass("showGitClientMac") ) {
$("body").removeClass("showGitClientMac");
}
else if ( $("body").hasClass("showGitClientWindows") ) {
$("body").removeClass("showGitClientWindows");
}
// And an appropriate class is added to the body
$("body").addClass("showGitClientTerminal");
});
// User clicks on #projectSite
$("#js-gitClientWindows").click( function() {
// Check if body has other class, if so remove it
if( $("body").hasClass("showGitClientMac") ) {
$("body").removeClass("showGitClientMac");
}
else if ( $("body").hasClass("showGitClientTerminal") ) {
$("body").removeClass("showGitClientTerminal");
}
// And an appropriate class is added to the body
$("body").addClass("showGitClientWindows");
});
// User clicks on #projectSite
$("#js-gitClientMac").click( function() {
// Check if body has other class, if so remove it
if( $("body").hasClass("showGitClientTerminal") ) {
$("body").removeClass("showGitClientTerminal");
}
else if ( $("body").hasClass("showGitClientWindows") ) {
$("body").removeClass("showGitClientWindows");
}
// And an appropriate class is added to the body
$("body").addClass("showGitClientMac");
});
// PROJECT SITE
// ----------- //
// User clicks on #projectSite
$("#js-projectSite").click( function() {
// Check if body has other class, if so remove it
if( $("body").hasClass("showUserSite") ) {
$("body").removeClass("showUserSite");
} else if ( $("body").hasClass("showGitClientMac") ) {
("body").removeClass("showGitClientMac");
} else if ( $("body").hasClass("showGitClientWindows") ) {
("body").removeClass("showGitClientWindows");
} else if ( $("body").hasClass("showGitClientTerminal") ) {
("body").removeClass("showGitClientTerminal");
}
// And an appropriate class is added to the body
$("body").addClass("showProjectSite");
});
// PROJECT SITE ----> GENERATE OR BUILD FROM SCRATCH
// ------------------------------------------------- //
// User clicks on #projectSite
$("#js-generateSite").click( function() {
// Check if body has other class, if so remove it
if( $("body").hasClass("showStartFromScratch") ) {
$("body").removeClass("showStartFromScratch");
}
// And an appropriate class is added to the body
$("body").addClass("showGenerateSite");
});
// User clicks on #projectSite
$("#js-startFromScratch").click( function() {
// Check if body has other class, if so remove it
if( $("body").hasClass("showGenerateSite") ) {
$("body").removeClass("showGenerateSite");
}
// And an appropriate class is added to the body
$("body").addClass("showStartFromScratch");
});
我知道有一种更精简,更清洁的方法。 有人能指出我正确的方向吗?
答案 0 :(得分:1)
您可以创建一个这样的简单函数:
function checkIfBodyHasClassIfSoRemoveIt(className, classNameAlt){
if($("body").hasClass(className)) {
$("body").removeClass(className);
} else if (classNameAlt && $("body").hasClass(classNameAlt)) {
$("body").removeClass(classNameAlt);
}
}
你可以这样使用:
// User clicks on #userSite
$("#js-userSite").click( function() {
// Check if body has other class, if so remove it
checkIfBodyHasClassIfSoRemoveIt("showProjectSite");
// And an appropriate class is added to the body
$("body").addClass("showUserSite");
});
// USER / ORGANISATION SITE ----> CHOOSE GIT CLIENT
// ----------------------------------------------- //
// Click event
$("#js-gitClientTerminal").click( function() {
// Check if body has other classes, if so remove it
checkIfBodyHasClassIfSoRemoveIt("showGitClientMac", "showGitClientWindows");
// And an appropriate class is added to the body
$("body").addClass("showGitClientTerminal");
});

我没有测试过这段代码,但应该可以使用!
