javascript - Putting PHP echo into a button's innerHTML doesn't work -



javascript - Putting PHP echo into a button's innerHTML doesn't work -

i have jquery code this:

$("#erase").click(function(){ $("#erase").attr("disabled", "disabled"); // prevent double-clicking $(this).html("erasing..."); $.post("erase.php", {target: $("#target").val(), criteria: $("#criteria").val()}, function(data){ $(this).html(data); // alter button's caption whatever erase.php echoes. settimeout(function(){ window.location.href = "index.php"; }, 3000); });

the target , criteria both html input tags , button declared button tag. expecting these happen when user clicks button:

button greyed out , text 'erasing...' erase.php called via ajax. erase.php delete row database, , takes several seconds complete. when ajax phone call completed, button text output of erase.php. either "success" or "failure" after 3 seconds, user brought home page.

but in case, step 3 fails. button gets stuck in 'erasing....' (the request does complete, however.)

side note: can't think of improve title question. if can come 1 me. please allow me know in comments. i'd appreciate it.

$(this) within of $.post not 1 had before. seek way

$("#erase").click(function(){ $("#erase").attr("disabled", "disabled"); // prevent double-clicking $(this).html("erasing..."); $this = $(this); $.post("erase.php", {target: $("#target").val(), criteria: $("#criteria").val()}, function(data){ $this.html(data); settimeout(function(){ window.location.href = "index.php"; }, 3000); });

assembly - What is the addressing mode for ld, add, and rjmp instructions? -

assembly - What is the addressing mode for ld, add, and rjmp instructions? - hey guys know ldi (load immediate) addressing mode set immediate , st instruction addressing mode set index. however, have no thought others curious are! thanks :) the addressing modes explained in instruction set, in first few pages. in table of instructions see operands instruction determine addressing mode. mode indicated arguments assembly instruction. for example, ld had several different ways of operating, depending on arguments. 1 of them ld rd,x d number of register, such ld r3,x . ld r3,-z else (although both indirect addressing). rjmp k relative addressing, jumping pc + k + 1. add rr,rd direct register addressing. result contained in rd. assembly avr instructions
