  • How to add a background to text only ?

    - by misha-moroshko
    I have a background image on top of which there is some text. It is very hard to read the text because of the background. I would like to add a white background just around the text itself, such that the text could be easily read. How can I accomplish this using CSS/Javascript/jQuery ?

  • Is strict mode more performant?

    - by sje397
    Does executing javascript within a browser in 'strict mode' make it more performant, in general? Do any of the major browsers do additional optimisation or use any other techniques that will improve performance in strict mode? Edit: Since none of the major engines actually implement strict mode, I'll rephrase slightly: Is strict mode intended, amongst its other goals, to allow browsers to introduce additional optimisations or other performance enhancements?

  • How to display a very long page like dzone.com?

    - by user360529
    Hi, If you ever visit dzone.com you'll notice that all the posts appear on 1 page only. When we scroll that page down, older posts will be added to the end of the page (and maybe some posts at the beginning of the page but outside the view port will be removed). My questions are: - how to know if the user scrolls down/up with javascript/jQuery? - how to know if the user is at the top of the page (they click Ctrl + Home)? Thank you.

  • body onload cache not clearing

    - by Mad Cow
    I'm using an image swapping function generated by Dreamweaver to allow an image to change when moused over. The images are small. I have a problem because the images are getting stored in cache and without clearing it out I cant get the new images to show. It works on some browsers, but unfortunately not on all... I've read about putting "a random query" into the javascript to force the page to reload, but I dont know where to put it (the code was generated for me by dreamweaver). A subset of my code is : <script type="text/javascript"> function MM_preloadImages() { //v3.0 var d=document; if(d.images){ if(!d.MM_p) d.MM_p=new Array(); var i,j=d.MM_p.length,a=MM_preloadImages.arguments; for(i=0; i<a.length; i++) if (a[i].indexOf("#")!=0){ d.MM_p[j]=new Image; d.MM_p[j++].src=a[i];}} } function MM_swapImgRestore() { //v3.0 var i,x,a=document.MM_sr; for(i=0;a&&i<a.length&&(x=a[i])&&x.oSrc;i++) x.src=x.oSrc; } function MM_findObj(n, d) { //v4.01 var p,i,x; if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) { d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);} if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.forms.length;i++) x=d.forms[i][n]; for(i=0;!x&&d.layers&&i<d.layers.length;i++) x=MM_findObj(n,d.layers[i].document); if(!x && d.getElementById) x=d.getElementById(n); return x; } function MM_swapImage() { //v3.0 var i,j=0,x,a=MM_swapImage.arguments; document.MM_sr=new Array; for(i=0;i<(a.length-2);i+=3) if ((x=MM_findObj(a[i]))!=null){document.MM_sr[j++]=x; if(!x.oSrc) x.oSrc=x.src; x.src=a[i+2];} } </script> </head> <body onload="MM_preloadImages('../images/navigation/social-about-us-over.jpg','../images/navigation/social-about-us.jpg','../images/navigation/social-activities-over.jpg','../images/navigation/social-ourservices-over.jpg','../images/navigation/social-howwework-over.jpg','../images/navigation/social-fundraising-over.jpg','../images/navigation/social-howtohelp-over.jpg','../images/navigation/social-contactus-over.jpg')"> My website is http://www.clockhouse.org.uk/ I'm sure there is a better way i could have written this, but if anyone can help me fix this code I'd be very grateful Many thanks

  • Passing arguments to a function?

    - by dfjhdfjhdf
    I need to learn how to pass an associative array to a function so that I could do the following within the function: function someName($argums) { if (gettype($argums) != 'array' || !array_key_exists('myOneKey', $argums) || !array_key_exists('myOtherKey', $argums)) { return false; } /*do other stuff*/ } (That's how I would do in PHP what I am looking for in JavaScript.)

  • Have a child window be notified when parent window goes to a different page?

    - by Heinrich Schmetterling
    i have a parent window and a child window. in javascript, i want a function in child window to be called whenever the parent window loads a new page. i'd like to use something similar to jQuery's $(document).ready() so that I don't have to worry about whether the parent is done loading yet - but ready() only appears to fire when the window loads the first page - but not when, say, a link is clicked in the parent and it loads a second page. any suggestions? thanks.

  • Bind event to a div appearing

    - by AndyC
    Can I create an event so I can execute some javascript whenever an element with a specific ID becomes visible or appears on the page? The element comes from a remote resource (so isn't in MY html code but appears on page load) and I'd like some code to run when it appears (and only if it appears, it may not appear every load). Thanks!
