[英]Checkboxes will not check in IE7 using Javascript, and yet no errors
好吧,我對這個完全困惑。
我有一個腳本,它從 JSON 對象接收一堆值並創建一堆復選框,然后根據它們的值選中或取消選中這些復選框。
該腳本在 IE8、Firefox3 等中正常工作......等等......
然而...
在 IE7 中,腳本無法勾選復選框。 它沒有顯示任何錯誤,據我所知,腳本運行得很好。 我只是沒有選中任何復選框,我不知道為什么......
shoppingCart['Update_Stock_Item_0_NRD%5FHAT2'] = {
'propeller': {
'label': 'propeller',
'optionValues': {
'on': {
'selected': 'selected'
},
'off': {
'selected': ''
},
'': new String()
}
},
'sunLogo': {
'label': 'sunLogo',
'optionValues': {
'on': {
'selected': 'selected'
},
'off': {
'selected': ''
},
'': new String()
}
},
'MSLogo': {
'label': 'sunLogo',
'optionValues': {
'on': {
'selected': 'selected'

'off': {

}
};
function stockInit() {
alert("BEGIN: stockInit()");
// TODO: You will recieve an "on" and an "off" option,
// One will have a "selected" attribute of "selected",
// and the other will have a "selected" attribute of ""

var optionContainer = document.getElementById(item + "_optionContainer");
for (var option in shoppingCart[item]) {
if (option != "blank") {
// // console.log("option: " + option);
var currentOption = shoppingCart[item][option]['optionValues'];
// // console.log("currentOption['on']['selected']: " + currentOption['on']['selected']);

// Really you only have to check the one, but just to be through-o
var selected = (currentOption['on']['selected'] == 'selected') ? true : false;
selected = (currentOption['off']['selected'] == 'selected') ? false : true;
var label = document.createElement("LABEL");
var labelText = document.createTextNode(shoppingCart[item][option]['label']);
var optionInput = document.createElement("INPUT");
var hiddenInput = document.createElement("INPUT");
optionInput.setAttribute("type", "checkbox");
optionInput.checked = selected;
optionInput.setAttribute("id", option);
alert(optionInput.id);
alert(optionInput.checked);
hiddenInput.setAttribute("type", "hidden");
hiddenInput.setAttribute("name", option);
hiddenInput.setAttribute("id", option + "_hiddenValue");
hiddenInput.setAttribute("value", (optionInput.checked) ? "on" : "off");
label.appendChild(optionInput);
label.appendChild(labelText);
label.appendChild(hiddenInput);
(function(id) {
optionInput.onclick = function() {
var hiddenInput = document.getElementById(id + "_hiddenValue");
hiddenInput.setAttribute("value", (this.checked == true) ? "on" : "off");
alert("this.id: " + this.id);
alert("this.checked: " + this.checked);
}
})(optionInput.id);
optionContainer.appendChild(label);
}
}
// // console.log("processing item of " + item + " complete");
}
alert("END: stockInit()");
}
並且請不要問我為什么要這樣做......我只能告訴你我無權訪問后端代碼......所以我得到了我得到的......
