链接的问题

[x0423]

一点编程的网站链接就会出现网站可以正常跳转，这要怎么解决0.0
动态的那一段代码
this._onFormElementClick = function() {
var element = window.event.srcElement;
if (element.disabled) {
return;
}

if (this.get_inPostBack()) {
return;
}

_postbackSettings = getPostbackSettings(element);

if (element.tagName == 'INPUT') {
var type = element.type;
if (type == 'submit') {
_additionalInput = element.name + '=' + encodeURIComponent(element.value);
}
else if (type == 'image') {
var x = window.event.offsetX;
var y = window.event.offsetY;
_additionalInput = element.name + '.x=' + x + '&' + element.name + '.y=' + y;
}
}
else if ((element.tagName == 'BUTTON') && (element.name.length != 0) && (element.type == 'submit')) {
_additionalInput = element.name + '=' + encodeURIComponent(element.value);
}
}
