Problems Making Get Request From Jquery

I'm trying to make an HTTP GET request using the jQuery get() function, but I'm having some trouble. Here's what my code looks like: // get the links on the page var pageLinks =

Solution 1:

Construct bdy after all pages are retrieved, i.e. store get results in a dictionary or array; wait for all gets to finish; then assemble them in the correct order.

Solution 2:

I tried this one and it works:

// get the links on the pagevar pageLinks = $('a');
var bdy 
// loop through each of the links
$(pageLinks).each(function(){
console.log(this);
       // make a GET request to the URL of this link
           $.get($(this).attr("href"), function(data) {

           // concatenate the return string with another
           bdy = bdy + data.toString();
           console.log(bdy);
       });

});

Solution 3:

As an example of what @muratgu has said:

var results = [];
var count = 0;

functionallDone() {
    var bdy = results.join("");
    // do stuff with bdy
}

// get the links on the pagevar pageLinks = $.find('#pageLinks');

// filter the links so we're left with the links we wantvar wantedLinks = $(pageLinks).find('a').filter(function (idx) {
    return $(this).attr('title') !== "Next Page";
});

// remember how many links we're working on
count = wantedLinks.length;

// loop through each of the links
wantedLinks.each(function (idx) {
    // make a GET request to the URL of this link
    $.get($(this).attr("href"), function (data) {
        console.log("here");
        var temp = parse_page(data);
        results[idx] = temp;

        // Decrement the count.
        count--;

        if (count === 0) {
            // All done.allDone();
        }
    });
});

You could go further and abstract this into a data type that can perform N async downloads, and then notify you when all are complete.

Solution 4:

I just found that there are modules that allow one to manage the control flow in JS. The ones I found are:

• Async
• Step

For help using the above modules, see my follow up question here.
