另开一个加分贴，webbrowser自动提交模拟鼠标的问题
有一个网页，尝试自动提交，那个元素的HTML为” <input id="password" autocomplete="off" class="textBoxInfo" type="password" data-bind="value: customer.password" onkeyup="return Fanex.Customer.CheckPassword(this, 'spnNewPwdIcon');" maxlength="10" style="position: relative;">“
简单 ((DispHTMLInputElement)all.item("password", 0)).value =“password123”，这样不行，JS报错，提示调用出错，我看了下，好像是onkeyup动作的JS函数生成的一些东西，如果用鼠标点一下，手动输入就可以，那如何模拟这个鼠标的动作呢，在这个网页上？ --------------------编程问答-------------------- 你这半天没人回答，我也不知道你想问什么，以前我做过一个qq控件自动登陆的，不知道对你有没有帮助。
HtmlElement u=webBrowser1.Document .All [“password"];//获取你需要的控件
u.SetAttribute("value","password123");//设置password的value
u.InvokeMember("click");//触发passwrod的click事件
自己慢慢研究吧，就帮你这么多了 --------------------编程问答-------------------- webbrowser我没干过，我干过直接操作IE，处理方式是将item拿到后转换为InputHTMLElement，然后调用这个对象的click()、focus()等等js都有的方法 --------------------编程问答-------------------- refer:
private void Form1_Load(object sender, EventArgs e)--------------------编程问答-------------------- 楼上的也可以，如果非要用mshtml 的话如下：
{
this.webBrowser1.Url = new Uri("http://www.baidu.com");
}
private void button1_Click(object sender, EventArgs e)
{
if (this.webBrowser1.ReadyState == WebBrowserReadyState.Complete)
{
HtmlElement text = this.webBrowser1.Document.All["kw"];
HtmlElement button = this.webBrowser1.Document.All["su"];
text.SetAttribute("value", "guwei4037");
button.InvokeMember("click");
}
}
hr1=pDisp->QueryInterface(IID_IHTMLDocument2,(void**)&pDocument);
hr=pDocument->get_all(&pCollection);
VARIANT varIndex, var;
for ( int i = 0; i <celem; i++ )
{
varIndex.vt = VT_UINT;
varIndex.lVal = i;
VariantInit(&var);
hr = pCollection->item(varIndex,var,&pDisp);
if ( hr == S_OK )
{
IHTMLElement *pElement;
IHTMLScriptElement *pScriptElement;
//hr = pDisp->QueryInterface(IID_IHTMLScriptElement,(void**)&pScriptElement);
hr = pDisp->QueryInterface(IID_IHTMLElement,(void**)&pElement);
pElement->get_innerText(&bstr);//这句赋值就行了 --------------------编程问答-------------------- private void Form1_Load(object sender, EventArgs e)
{
this.webBrowser1.Url = new Uri("http://www.baidu.com");
}
private void button1_Click(object sender, EventArgs e)
{
if (this.webBrowser1.ReadyState == WebBrowserReadyState.Complete)
{
HtmlElement text = this.webBrowser1.Document.All["kw"];
HtmlElement button = this.webBrowser1.Document.All["su"];
text.SetAttribute("value", "guwei4037");
button.InvokeMember("click");
}
}
这个不错,不过最好TRY一下.ALL这样不是好确定的.你要保证你网页加载完成后才OK. --------------------编程问答-------------------- if (this.webBrowser1.ReadyState == WebBrowserReadyState.Complete)
有个ISBUSY加上就更好了.

回复：sunyaxingqq这样U为NULL，等多久也是，好像是找不到。还有其它的回贴者，看清楚，基本的赋值操作我都会，我要的模拟鼠标按下弹起这样子的。 --------------------编程问答--------------------
IHTMLElement i=(IHTMLElement)all.item("password", 0);
i.click();
if (((DispHTMLInputElement)all.item("password", 0)).value == null)
((DispHTMLInputElement)all.item("password", 0)).value = =“password123”；这样没有效果，不一定是在ONKEYUP里记录的，好像没有跟踪到，可能是在样式或者BING里生成的JS，确还是根据鼠标动作形成的。大家给点思路 --------------------编程问答--------------------
你要明白提交表单原理就不会那么做了 看这个http://download.csdn.net/detail/zhuankeshumo/5656679

webBrowser可以执行脚本（而并不需要文档中写了这些脚本）。你可以先执行脚本 Fanex.Customer.CheckPassword(password, 'spnNewPwdIcon');
然后再复制。 --------------------编程问答-------------------- 然后再复制 --> 然后再赋值
而且 onkyeup 可不是鼠标操作，而是键盘按键抬起操作。 --------------------编程问答-------------------- form1.submit(); --------------------编程问答-------------------- 除 --------------------编程问答-------------------- 好像不是KEYUP的关系。可能是data-bind="value: customer.password" 的关系，我不明白这是什么意思，
调用了一个websource.axd?hhh里的JS， 好像是一个专门处理事件的东东，这个怎么执行JS
showDown: function (elementInput, message, xPos, pointerXPos, yPos, pointerYPos, height, timeout) {
// <span class="fHintDown"><span>This is the message.<span><span class="hint-pointer"> </span></span>
var hint = document.getElementById('fHintDown');
var hintPointer = null;
if (hint == null) {
var hint = document.createElement("SPAN");
hint.className = 'hint';
var hintMsg = document.createElement("SPAN");
hint.appendChild(hintMsg);
hintPointer = document.createElement("SPAN");
hintPointer.className = 'hint-pointer-down';
hint.appendChild(hintPointer);
hint.id = 'fHintDown';
hint.style.top = '10px';
hint.style.left = '10px';
hint.style.zIndex = 999999;
hint.onclick = function () { // Hide onclick
hint.style.display = 'none';
};
document.body.appendChild(hint);
};
hintPointer = hint.lastChild;
hint.firstChild.innerHTML = message;
if (this.timeOutHideTooltip) {
clearTimeout(this.timeOutHideTooltip);
this.timeOutHideTooltip = null;
};
if (typeof (timeout) == 'undefined') {
timeout = 1000;
}
this.timeOutHideTooltip = setTimeout(function () {
if (hint == null) {
return;
}
hint.style.display = 'none';
}, timeout); // Auto hide in 1s
if (elementInput != null) {
if (typeof xPos == 'undefined') {
xPos = 0;
}
if (typeof pointerXPos == 'undefined') {
pointerXPos = 10;
}
if (typeof yPos == 'undefined') {
yPos = -45;
}
if (typeof (pointerYPos) == 'undefined') {
pointerYPos = 38;
}
if (typeof (height) == 'undefined') {
height = 18;
}
hint.style.height = height + 'px';
hintPointer.style.left = (pointerXPos + 'px');
hintPointer.style.top = (pointerYPos + 'px');
var pos = Validators.utils.findPosRelativeToViewport(elementInput);
hint.style.left = (pos[0] + xPos) + 'px';
hint.style.top = (pos[1] + yPos) + 'px';
elementInput.onchange = function () {
hint.style.display = 'none';
};
elementInput.focus();
};
hint.style.display = 'block';
}
