AJAX load Wordpress Content_问答_开发者_运维开发者技术经验分享

I have been following an AJAX tutorial to try and load my wordpress post content onto the homepage of my website without having the page reload.

I am not sure why, but when the links are clicked it is still navigating to the page rather than loading the content into the div I specified. Anyway, it is all a bit too much for me and I would love some guidance!

The tutorial link I have been following is - http://net.tutsplus.com/tutorials/javascript-ajax/how-to-load-in-and-animate-content-with-jquery/

My live website is - http://www.mathewhood.com

My current code is -

n.b. For those of you not familiar with wordpress, it has a header.php, template.php and footer.php. Each template file calls the header and the footer as to avoid duplication of code. I will link them all though. I have also included the single_portfolio page, which is where the page would normally go to.

ajax.js

$(document).ready(function() {  

    // Check for hash value in URL  
    var hash = window.location.hash.substr(1);  
    var href = $('.caption a').each(function(){  
        var href = $(this).attr('href');  
        if(hash==href.substr(0,href.length-5)){  
            var toLoad = hash+'.html #content';  
            $('#content').load(toLoad)  
        }  
    });  

    $('#.caption a').click(function(){  

    var toLoad = $(this).attr('href')+' #content';  
    $('#content').hide('fast',loadContent);  
    $('#theContainer').remove();  
    $('#wrapper').append('<span id="load">LOADING...</span>');  
    $('#theContainer').fadeIn('normal');  
    window.location.hash = $(this).attr('href').substr(0,$(this).attr('href').length-5);  
    function loadContent() {  
        $('#content').load(toLoad,'',showNewContent())  
    }  
    function showNewContent() {  
        $('#content').show('normal',hideLoader());  
    }  
    function hideLoader() {  
        $('#theContainer').fadeOut('normal');  
    }  
    return false;  

    });  
});

I didn't put in footer.php because it is isn't necessary for you to see it.

Please help me out if you can, I really have no idea where to go from here :(

In your ajax.js the second line should be

var href = $('.recentPost a').each(function(){ });

because the div with the class caption does not contain the href links you need. Make this change and check if it works.

And also the click function should be one the class recentPost not on caption !!!
