html组件不可输入(只读)同时任何组件都有效

复制代码 代码如下:

/**
* 将页面设置为只读
*/
var setReadOnly = function()
{
var input = $("input");
input.each(function(i)
{
$(this).attr("onfocus", "this.blur();return false;");
$(this).wrap(function()
{
return '<span onmousemove="this.setCapture();" onmouseout="this.releaseCapture();" />';
});
});
var select = $("select");
select.each(function(i)
{
$(this).attr("onfocus", "this.blur();return false;");
$(this).wrap(function()
{
return '<span onmousemove="this.setCapture();" onmouseout="this.releaseCapture();" />';
});
});
var textarea = $("textarea");
textarea.each(function(i)
{
$(this).attr("onfocus", "this.blur();return false;");
$(this).wrap(function()
{
return '<span onmousemove="this.setCapture();" onmouseout="this.releaseCapture();" />';
});
});
var img = $("img");
img.each(function(i)
{
$(this).attr("onfocus", "this.blur();return false;");
$(this).wrap(function()
{
return '<span onmousemove="this.setCapture();" onmouseout="this.releaseCapture();" />';
});
});
}
