  • 开发中可能会用到的几个 jQuery 小提示和技巧

    1、禁止右键

      

    $(document).ready(function() {
        //catch the right-click context menu
        $(document).bind("contextmenu",function(e) {                
            //warning prompt - optional
            alert("No right-clicking!");
     
            //delete the default context menu
            return false;
        });
    });
    

     2、文本缩放

    $(document).ready(function() {
        //find the current font size
        var originalFontSize = $('html').css('font-size');
     
        //Increase the text size
        $(".increaseFont").click(function() {
            var currentFontSize = $('html').css('font-size');
            var currentFontSizeNumber = parseFloat(currentFontSize, 10);
     
            var newFontSize = currentFontSizeNumber*1.2;
            $('html').css('font-size', newFontSize);
            return false;
        });
     
        //Decrease the Text Size
        $(".decreaseFont").click(function() {
            var currentFontSize = $('html').css('font-size');
            var currentFontSizeNum = parseFloat(currentFontSize, 10);
     
            var newFontSize = currentFontSizeNum*0.8;
            $('html').css('font-size', newFontSize);
            return false;
        });
     
        // Reset Font Size
        $(".resetFont").click(function(){
        $('html').css('font-size', originalFontSize);
      });
    });
    

     3、新窗口打开连接

    $(document).ready(function() {
        //select all anchor tags that have http in the href
        //and apply the target=_blank
        $("a[href^='http']").attr('target','_blank');
    });
    

     4、样式表切换

    $(document).ready(function() {
        $("a.cssSwap").click(function() {
            //swap the link rel attribute with the value in the rel   
            $('link[rel=stylesheet]').attr('href' , $(this).attr('rel'));
        });
    });
    

     5、回到顶部

    $(document).ready(function() {
        //when the id="top" link is clicked
        $('#top').click(function() {
            //scoll the page back to the top
            $(document).scrollTo(0,500);
        }
    });
    

     6、获取鼠标的 X、Y 坐标

    $(obj).mousemove(function(e){
        //display the x and y axis values inside the P element
        $('p').html("X Axis : " + e.pageX + " | Y Axis " + e.pageY);
    });
    

     7、检测当前鼠标的坐标

    $(document).ready(function() {
        $(obj).mousemove(function(e){
        $('# MouseCoordinates ').html("X Axis Position = " + e.pageX + " and Y Axis Position = " + e.pageY);
    });
