JS.GetAllChild(element,deep,condition)使用介绍

window.GetAllChild = function (element, deep, condition) { 
if (!!!deep) { deep = 1; } 
if (!!!condition || condition == '') { condition = '1==1'; } 
deep--; 
if (!!!element || !!!element.childNodes || element.childNodes.length <= 0) { return []; } 
var result = new Array(); 
for (var i = 0; i < element.childNodes.length; i++) { 
if (element.style && (element.style.visibility == 'hidden' || element.style.display == 'none')) { 
continue; 
} 
var child = element.childNodes[i]; 
if (eval(condition)) { 
result.push(child); 
} 
if (deep > 0) { 
result = result.concat(GetAllChild(child, deep, condition)); 
} 
} 
return result; 
}
