通過js判斷訪問來自移動端還是pc端從而去控制事件的邏輯或者元素的顯示
通過js判斷訪問來自手機端還是pc端
function browserRedirect() {
var accessTerminal = "";var sUserAgent = navigator.userAgent.toLowerCase();
var bIsIpad = sUserAgent.match(/ipad/i) == "ipad";
var bIsIphoneOs = sUserAgent.match(/iphone os/i) == "iphone os";
var bIsMidp = sUserAgent.match(/midp/i) == "midp";
var bIsUc7 = sUserAgent.match(/rv:1.2.3.4/i) == "rv:1.2.3.4";
var bIsUc = sUserAgent.match(/ucweb/i) == "ucweb";
var bIsAndroid = sUserAgent.match(/android/i) == "android";
var bIsCE = sUserAgent.match(/windows ce/i) == "windows ce";
var bIsWM = sUserAgent.match(/windows mobile/i) == "windows mobile";
if (bIsIpad || bIsIphoneOs || bIsMidp || bIsUc7 || bIsUc || bIsAndroid || bIsCE || bIsWM) {
accessTerminal = "notpc";
} else {
accessTerminal = "pc";
}
return accessTerminal;
}
手機端限制長按彈出複製選單（限制手機端瀏覽器複製功能）
$(function(){
var accessTerminal = browserRedirect();
if(accessTerminal!="pc"){
$('#endText').css({"-webkit-touch-callout":"none","-webkit-user-select":"none","-khtml-user-select":"none",
"-moz-user-select":"none","-ms-user-select":"none","user-select":"none"});
$('#endText').attr("unselectable","on");
$('#endText').attr("onselectstart","return false;");
/*document.body.onselectstart=document.body.oncontextmenu=function(){return false;};
if (typeof(document.onselectstart) != "undefined") {
// IE下禁止元素被選取
document.onselectstart = function (event){
if(event.target.tagName!="INPUT"){
return false;
}
}
} else {
// firefox下禁止元素被選取的變通辦法
document.onmousedown = function (event){
if(event.target.tagName!="INPUT"){
return false;
}
}
document.onmouseup = function(event){
if(event.target.tagName!="INPUT"){
return false;
}
}
}*/
}
});
通過js判斷訪問來自那款瀏覽器
function visitBrowser(){
var userAgent = navigator.userAgent; //取得瀏覽器的userAgent字串
var isOpera = userAgent.indexOf("Opera") > -1;
if (isOpera) {
return "Opera"
};
if (userAgent.indexOf("Firefox") > -1) {
return "FF";
}
if (userAgent.indexOf("Chrome") > -1){
return "Chrome";
}
if (userAgent.indexOf("Safari") > -1) {
return "Safari";
}
if (userAgent.indexOf("compatible") > -1 && userAgent.indexOf("MSIE") > -1 && !isOpera) {
return "IE";
};
}
