我建议你使用 jQuery,
我用它从我的 json 项目创建了一个表单,我希望这会有所帮助......
function jsonFormCreator(frmJSON)
{
var createdHTML = ""; var elementType, id;
console.log(JSON.stringify(frmJSON));
for(item in frmJSON)
{
formElement = frmJSON[item]; elementType = formElement.elementType; id = formElement.id;
if(elementType == "input")
{
createdHTML += "<input id='" + id +"'";
if(formElement.type == "checkbox")
{createdHTML += " type='" + formElement.type + "' checked='" + formElement.checked + "'";}
else{createdHTML += "type='" + formElement.type + "' value='" + formElement.value + "' onclick='" + formElement.onclick + "'";}
createdHTML += "/><br>"
}
else if(elementType == "textarea")
{createdHTML += "<textarea id='" + formElement.id + "' rows='" + formElement.rows + "' cols='" + formElement.cols + "' value='" + formElement.value + "'></textarea><br>";}
else if(elementType == "select")
{
var options = formElement.values;
createdHTML += "<select id='" + formElement.id+ "'>";
for(i = 0 ; i < options.length ; i++)
{createdHTML += "<option value='" + options[i][0] + "'>" + options[i][1] + "</option>";} //Adding each option
createdHTML+= "</select><br>";
}
}
console.log("Complete");console.log(createdHTML);
document.getElementById('mainContainer').innerHTML = createdHTML;//Adding to the DOM
}
我的 JSON 看起来像这样
{
"0": {
"elementType": "input",
"id": "frm1",
"type": "text",
"value": "form Liam",
"label": "Test Text Input"
},
"itemBTN": {
"elementType": "input",
"id": "frmAlert",
"type": "button",
"onclick" : "loader(homePage);",
"value": "Home Page",
"label": ""
},
"item2": {
"elementType": "textarea",
"id": "frm2",
"rows": 5,
"cols": 30,
"value": "helddddddddlo",
"label": "Test Textarea"
},
"item3": {
"elementType": "select",
"id": "frm3",
"values": [
[
"value1",
"Pick Me"
],
[
"value2",
"UserDis2"
],
[
"value3",
"UserDis3"
],
[
"value4",
"UserDis4"
],
[
"value5",
"UserDis5"
],
[
"value6",
"UserDis6"
]
],
"label": "Test Select"
},
"item4": {
"elementType": "input",
"id": "frm4",
"label": "Checkbox",
"type": "checkbox",
"checked": true
}
}
这段代码将表单添加到我的 div 标签中,id 为 mainContainer 我知道它有很多代码,但我希望它有所帮助!
