麻烦隐藏/显示div使用DOM / js / css [英] Trouble hiding/showing divs in using DOM/js/css
问题描述
我试图做一个调试器,将用一些变量dynamiaclly创建。左侧div上的名称需要显示对应的变量描述,变量ID和初始值的div以及另一个div,当变量以后更新时,将显示历史和锁定状态。我在哪里我有麻烦正确地添加显示/隐藏到dom我认为。一切都开始隐藏,然后当我点击一个名称时,该名称的变量显示,但下一次点击不隐藏前者的值。还有任何清理/优化建议吗?
I am trying to make a debugger that will be dynamiaclly created with some variables. The names on the left div need to show a div for the corresponding variables Description,Variable ID, and initial Value as well as another div that will show history and lock status when variables are updated later. Where I am having trouble is properly adding the show/hide to the dom I think. Everything starts hidden and then when I click a name the Variables for that name show up but the next click doesn't hide the values from the former. Also any cleanup/optimization advice?
<script type="text/javascript">
var variableIDArray = {};
function loadVariables(variables) {
if (typeof variables != "object") { alert(variables); return; }
var namearea = document.getElementById('namearea');
var description = document.getElementById('description');
var varid = document.getElementById('varid');
var initialvalue = document.getElementById('initialvalue');
var valuelock = document.getElementById('valuelock');
for (var i = 0; i < variables.length - 1; i++) {
var nameDiv = document.createElement('div');
nameDiv.id = variables[i].variableID + "namearea";
nameDiv.className = "nameDiv";
nameDiv.onclick = (function (varid) {
return function () { showvariable(varid); };
})(variables[i].variableID);
nameDiv.appendChild(document.createTextNode(variables[i].name));
namearea.appendChild(nameDiv);
var descriptionDiv = document.createElement('div');
descriptionDiv.id = variables[i].variableID + "description";
descriptionDiv.className = "descriptionDiv";
descriptionDiv.appendChild(document.createTextNode("Description : " + variables[i].description));
description.appendChild(descriptionDiv);
var varidDiv = document.createElement('div');
varidDiv.id = variables[i].variableID + "varid";
varidDiv.className = "varidDiv";
varidDiv.appendChild(document.createTextNode("Var ID : " + variables[i].variableID));
varid.appendChild(varidDiv);
var initialvalueDiv = document.createElement('div'); ;
initialvalueDiv.id = variables[i].variableID + "initialvalue";
initialvalueDiv.className = "initialvalueDiv";
initialvalueDiv.appendChild(document.createTextNode("Initial Value : " + variables[i].value));
initialvalue.appendChild(initialvalueDiv);
var valuelockDiv = document.createElement('div');
valuelockDiv.id = variables[i].variableID + "valuelock";
valuelockDiv.className = "valuelockDiv ";
valuelockDiv.appendChild(document.createTextNode("Value : " + variables[i].value));
valuelockDiv.appendChild(document.createTextNode("Lock : " + variables[i].locked.toString()));
valuelock.appendChild(valuelockDiv);
variableIDArray[variables[i].variableID];
}
};
function showvariable(varid) {
for (v in variableIDArray)
hide(variableIDArray[v]);
show(varid + "description");
show(varid + "varid");
show(varid + "initialvalue");
show(varid + "valuelock");
}
function show(elemid) {
document.getElementById(elemid).style.display = "block";
}
function hide(elemid) {
document.getElementById(elemid).style.display = "none";
}
