该方法constructBuilder()
不应无限执行,因为它设置为仅循环 10 次,并且 data.length 的值永远不会改变。
这个循环和方法实际上工作得很好,直到我在循环中调用另一个方法。
getOptions(type)
当我在这个循环中调用方法时,值的i
变化非常奇怪,并且总是遵循这种模式:
1st run: i=0
2nd run: i=1
3rd run: i=3
4th run: i=5
5th run: i=6
6th run: i=4
7th run: i=4
8th run: i=4
nth run: i=4
的值i
被卡在 4,不会增加并且循环无限运行!
为什么会这样??
这是代码:
var data = [["Text Array", "Some more text", "btnText", "btn2text"],
["Text2", "2: more text", "btnText2", "btn2text2"],
...
];
var products, order;
function initialise() {
products = loadProducts();
order = new Order();
constructBuilder();
}
function constructBuilder() {
var qb_boxes_innerHTML = "";
for (i=0; i<data.length; i++) {
alert("i="+i + "; data length="+data.length);
var box_innerHTML = "<table width=100% height=100% cellpadding=0; cellspacing=0; border=0>";
box_innerHTML += "<tr><td width=100% height=\"50px\">" + data[i][0] + "</td></tr>";
box_innerHTML += "<tr><td width=100% class=\"scroll\" valign=\"top\">" + data[i][1] + getOptions(i) + "</td></tr>";
box_innerHTML += "<tr><td width=100% height=\"50px\" align=\"right\" valign=\"middle\"><form action=\"javascript:next();\"><input type=\"button\" value=\""
+ data[i][2] + "\" onClick=\"prev();\"/><input id=\"continueBtn\" type=\"submit\" value=\""
+ data[i][3] + "\" disabled/></form></td></tr>";
box_innerHTML += "</table>";
qb_boxes_innerHTML += "<div id=\"qb_box" + i + "\" class=\"qb_box\" style=\"visibility: hidden;\">" + box_innerHTML + "</div>";
}
document.getElementById("qb_boxes").innerHTML = qb_boxes_innerHTML;
document.getElementById("qb_box0").style.visibility = "";
}
function getOptions(type) {
var optionsList = getProducts(products, type);
var options_html = "";
for (i=0; i<optionsList.length; i++) {
options_html += "<input id=\"check"+type+"_"+i+"\" type=\"checkbox\"/>" + optionsList[i].name + "<BR/>";
}
return options_html;
}
function getProducts(productList, type) {
var productsOfType = new Array();
for (i=0; i<productList.length; i++) {
if (productList[i].type == type)
productsOfType.push(productList[i]);
}
return productsOfType;
}
