First, you need to determine whether you want to disable the global control or the specified control. For example, I only need to disable the up and down keys of a text box. Copy codeThe Code is as follows: NoExec = function (event ){ Var k = event. which | event. keyCode; If (k = 13 | k = 38 | k = 40 ){ If ($ ("# atWinByArea"). attr ("id ")){ If (event. which) {// Firefox Event. preventDefault (); } Else {// IE, Chrome Event. returnValue = fa

First you want to make sure you want to disable global or specified controls, such as I just disable the upper and lower keys of a text box Copy Code code as follows: noexec = function (event) { var k = Event.which | | Event.keycode; if (k = = | | k = = | | k = = 40) { if ($ ("#atWinByArea"). attr ("id")) { if (Event.which) {//Firefox Event.preventdefault (); else {//ie, Chrome Event.returnvalue = false; } } } Downat (event); }
