JavaScript在Maximo中强制执行OnChange [英] JavaScript force an OnChange in Maximo
问题描述
我目前正在为Maximo开发一个书签，这是一个Java EE应用程序，我需要填充一些输入框。
I'm currently working on a Bookmarklet for Maximo, which is a Java EE application, and I need to populate a few input boxes.
通常在使用时将数据输入框中，他们单击一个弹出按钮，然后他们搜索要添加到脚本中的值。或者，他们可以键入名称并按Tab / Enter，然后将其转换为大写字母，并在后台执行一些操作（不确定其确切功能）。
Generally when a use inputs data into the box they click a button that gives them a popup and they search for the value to be added to the script. Or they can type the name and hit tab/enter and it turns it to capital letters and does a few things in the background (not sure what it does exactly).
我当前使用
Javascript: $('mx1354').value = "KHBRARR"; $('mx1354').ov= "KHBRARR";
但是它不能像我需要的那样工作。它将输入框设置为所需的值，但是它不运行后台功能，因此当我按下保存按钮时，它不会将其识别为任何更改并丢弃了我在框中输入的内容。
But it does not work like I need it to. It set's the input box to the value needed, but it doesn't run the background functions so when I hit the save button it doesn't recognize it as any changes and discards what I put into the box.
如何模拟已按下的选项卡/输入按钮？
How could I simulate a tab/enter button has been pressed?
到目前为止，我尝试将onchange，focus /模糊并单击函数（不确定我是否正确调用了函数）。
So far I've tried to call the onchange, focus/blur, and click functions (Not 100% sure if I called them correctly).
dojo库是应用程序的一部分，所以我不确定是否可以如果功能或jQuery会引起冲突，请使用它。
The dojo library is part of the application, so I'm not sure if I can use one if it's feature or if jQuery would cause a conflict.
PS这需要在IE中运行。
P.S. This needs to run in IE.

推荐答案
之后一段时间我发现，为了通过JavaScript更改页面，您需要提交一个隐藏的表单，以便可以在后端进行验证。
After some time I found that in order to make a change to the page via JavaScript you need to submit a hidden form so it can verify on the back-end.
这里是
cc : function(e,v){
e.focus(); //Get focus of the element
e.value = v; //Change the value
e.onchange(); //Call the onchange event
e.blur(); //Unfocus the element
console.log("TITLE === "+e.title);
if(e.title.indexOf(v) != -1) {
return true; //The value partially matches the requested value. No need to update
} else {
//Generate an hidden form and submit it to update the page with the new value
var hiddenForm = getHiddenForm();
var inputs = hiddenForm.elements;
inputs.namedItem("changedcomponentid").value = e.id;
inputs.namedItem("changedcomponentvalue").value = v;
inputs.namedItem("event").value = "X"; //Send a Dummy Event so the script see's its invalid and sets the right Event
submitHidden();
}
//Value isn't set to the required value so pass false
return false;
}
