I have made a simple dynamic form to generate input boxes.
<body>
<div id="main1">
<input type="button" onclick="addSelectBox ()" name="clickme" value="+"/>
<input type="button" onclick="removeSelect();" value="-"/>
<input type="button" onclick="xmlData();" value="XML" />
</div>
<div id="main">
</div>
</body>
Here's the javascript code:
(function () {
var selele=0;
var brindex=0;
function addSelectBox() {
selele = selele + 1;
var spantag = document.createElement("span");
spantag.setAttribute("id", selele);
var parentDiv = document.getElementById("main");
var selectElement = document.createElement("select");
var selectElement1 = document.createElement("select");
var selectElement2 = document.createElement("select");
var selectElement3 = document.createElement("select");
var arr = new Array("Stocks", "MutualFunds");
var arr2 = new Array("individual", "401k", "IRA");
var arr3 = new Array("contains", "equals");
var arr4 = new Array("scrapedaccounttype", "scrapedtransactiontype");
var textbox = document.createElement('input');
for (var i = 0; i < arr.length; i++) {
var option = new Option(arr[i]);
selectElement.options[selectElement.options.length] = option;
}
for (var i = 0; i < arr2.length; i++) {
var option = new Option(arr2[i]);
selectElement1.options[selectElement1.options.length] = option;
}
for (var i = 0; i < arr3.length; i++) {
var option = new Option(arr3[i]);
selectElement2.options[selectElement2.options.length] = option;
}
for (var i = 0; i < arr4.length; i++) {
var option = new Option(arr4[i]);
selectElement3.options[selectElement3.options.length] = option;
}
spantag.appendChild(selectElement);
spantag.appendChild(selectElement1);
spantag.appendChild(selectElement2);
spantag.appendChild(selectElement3);
spantag.appendChild(textbox);
parentDiv.appendChild(spantag);
linebreak();
};
function removeSelect() {
var parentDiv = document.getElementById("main");
var removetg = document.getElementById(selele);
if (selele != 1) {
parentDiv.removeChild(removetg);
selele = selele - 1;
} else {
parentDiv.removeChild(removetg);
parentDiv.innerHTML = "";
selele = selele - 1;
}
removeBreak();
};
function linebreak() {
brindex = brindex + 1;
var brtag = document.createElement("br");
brtag.setAttribute("id", brindex);
var parentDiv = document.getElementById("main");
parentDiv.appendChild(brtag);
};
function linespace() {
var myElement = document.createElement("span");
myElement.innerHTML = "           ";
var parentDiv = document.getElementById("main");
parentDiv.appendChild(myElement);
};
function removeBreak() {
var myElement = document.getElementById(brindex);
var parentDiv = document.getElementById("main");
brindex = brindex - 1;
parentDiv.removeChild(myElement);
};
function xmlData() {
xmlDoc = loadXMLDoc("data.xml");
newel = xmlDoc.createElement("edition");
x = xmlDoc.getElementsByTagName("span")[0];
x.appendChild(newel);
};
});
I can't get it to work on jsFiddle, the buttons don't work.
They work fine if I embed it in a tag.
Can anybody help me fix them.
EDIT: I guess i added anonymously because I wanted the var selele and brindex
globally for all these functions.
I have made the code changes.
Your functions are within an anonymous function and thus not available from outside.
First remove the code from the anonymous function (see here: http://jsfiddle.net/uH84W/6/ ), then fix the console errors you get (I assume that's not the whole code).
function addSelectBox() {...
在您的小提琴中选择onload,但是将onload更改为无扭曲或无扭曲,现在工作正常
