Call parent Javascript function from inside an iframe

阅读更多关于 Call parent Javascript function from inside an iframe

I have a iframe (in my domain), that iframe has a file iframe.js . My parent document has a file parent.js . I need to call a function that is in parent.js , from a function that is in iframe.js . I tried doing window.parent.myfunction() this function is in the parent.js file. But, it didn't work. Only when I put the function on the parent page (I mean in the HTML), then it worked. Any idea how to get this to work? Try just parent.myfunction() . Also be 100% sure that the parent.js is included in your parent document. I know this is an old question, but in case the accepted answer doesn't work

How to call a parent method from child class in javascript?

阅读更多关于 How to call a parent method from child class in javascript?

I've spent the last couple of hours trying to find a solution to my problem but it seems to be hopeless. Basically I need to know how to call a parent method from a child class. All the stuff that I've tried so far ends up in either not working or over-writing the parent method. I am using the following code to set up OOP in javascript: // SET UP OOP // surrogate constructor (empty function) function surrogateCtor() {} function extend(base, sub) { // copy the prototype from the base to setup inheritance surrogateCtor.prototype = base.prototype; sub.prototype = new surrogateCtor(); sub

How do I get the n-th level parent of an element in jQuery?

阅读更多关于 How do I get the n-th level parent of an element in jQuery?

When I want to get, for example, the 3rd level parent of the element I must write $('#element').parent().parent().parent() Is there a more optimal method for this? Since parents() returns the ancestor elements ordered from the closest to the outer ones, you can chain it into eq() : $('#element').parents().eq(0); // "Father". $('#element').parents().eq(2); // "Great-grandfather". Depends on your needs, if you know what parent your looking for you can use the .parents() selector. E.G: http://jsfiddle.net/HenryGarle/Kyp5g/2/ <div id="One"> <div id="Two"> <div id="Three"> <div id="Four"> </div> <

jQuery multiple parent() calls

阅读更多关于 jQuery multiple parent() calls

I have this jQuery: $(this).parent().parent().find(".license_tooltip").stop(true, true).fadeIn(200); The $(this) object is nested within two div s like this: <div> <div> <a href="">$(this) object</a> </div> <div> <a href="">object to fade in</a> </div> </div> Can someone point me in the right direction to making my jQuery more streamlined? The structure presented above is replicated multiple times, so using classes and IDs is impossible. You can use a class (or any other selectable attribute) and .closest() to claim to the parent you want, like this: <div class="container"> <div> <a href="">$

Is there a way to access parent modules in Python

阅读更多关于 Is there a way to access parent modules in Python

问题 I need to know if there is a way to access parent modules from submodules. If I import submodule: from subprocess import types I have types - is there some Python magic to get access to subprocess module from types ? Something similar to this for classes ().__class__.__bases__[0].__subclasses__() . 回答1: If you've accessed a module you can typically get to it from the sys.modules dictionary. Python doesn't keep "parent pointers" with names, particularly because the relationship is not one-to

问题 parent.php: require_once 'child.php'; child.php: echo __FILE__; It will show '.../child.php' How can i get '.../parent.php' 回答1: print $_SERVER["SCRIPT_FILENAME"]; 回答2: The chosen answer only works in environments that set server variables and specifically won’t work from a CLI script. Furthermore, it doesn't determine the parent, but only the topmost script file. You can do almost the same thing from a CLI script by looking at $argv[0], but that doesn’t provide the full path. The environment
