我目前正在构建一个使用jQuery进行动画处理的布局,并且正在使用.width()找出div的宽度。但是,有时在激活TypeKit之前会得到.width()(因此给出了错误的宽度)。

有没有一种方法可以使用if statement检查TypeKit是否已加载?

最佳答案

就在这里。

可以在回调(docs)中使用Typekit.load,而不用在try{Typekit.load();}catch(e){}标记中调用通常的head

try {
  Typekit.load({
    loading: function() {
      // JavaScript to execute when fonts start loading
    },
    active: function() {
      // JavaScript to execute when fonts become active
      // this is where you want to init your animation stuff
    },
    inactive: function() {
      // JavaScript to execute when fonts become inactive
    }
  })
} catch(e) {}


从字面上看,我只是为我自己的项目完成了此操作,但是我无法更改该代码。因此,如果您处于相同的情况,请尝试以下操作:

// configure these
var check_interval = 100; // how many ms to leave before checking again
var give_up_after_ms = 2000; // how many ms before we consider the page loaded anyway.

// caches etc
var count = 0;
var count_limit = give_up_after_ms / check_interval;
var html = $("html");
var font_loaded_check_interval;

var check_load_status = function(callback) {

    if(html.hasClass("wf-active") || count >= count_limit) {

        // fonts are loaded or give_up_after_ms was reached

        if(font_loaded_check_interval) {
            clearInterval(font_loaded_check_interval);
            font_loaded_check_interval = null;
        }

        // call the callback
        callback.call(this);
        return true;

    }

    count++;
    return false;

};

function doneCallback() {
    // code to run when fonts are loaded or timeout reached
    alert("Done");
}

// check on initial run of JS, and if not ready, start checking at regular intervals.
if( ! check_load_status(doneCallback)) {
    font_loaded_check_interval = setInterval(function() {
        check_load_status(doneCallback);
    }, check_interval);
}
