DOM正在創建無序的HTML元素

Question

我正在嘗試使用DOM動態創建HTML元素。

這些元素都是繪製的，只是它們看起來不合理。

例如這裏是它創建並添加元素的功能是這樣的：

function inputForms(goal){ 
if(goal=="fatloss"){ 
    // remove any form previous created 
    $("#"+"input_child").remove(); 
    // create new form section 
    createDiv("input_parent","input_child"); 
    // create form elements 
    Label("input_parent","curr_act_label","curr_act_lvl","Current Activity Level:"); 
    selectInputElement("input_child","curr_act_lvl"); 
    selectOption("curr_act_lvl","Please Select Your Current Activity Level...", "none"); 
    selectOption("curr_act_lvl","No Exercise or Desk Job", "1.25"); 
    selectOption("curr_act_lvl","Little Daily Activity or Light Exercise 1-3 Days Weekly", "1.35"); 
    selectOption("curr_act_lvl","Moderately Active Lifestyle or Moderate Exercise 3-5 Days Weekly", "1.55"); 
    selectOption("curr_act_lvl","Physically Demanding Lifestyle or Hard Exercise 6-7 Days Weekly", "1.75"); 
    selectOption("curr_act_lvl","Hardcore Lifestyle 24/7", "1.95"); 

    Label("input_parent","curr_bodyfat_label","curr_bodyfat_input","Current Bodyfat:"); 
    InputField("input_parent","curr_bodyfat_input","text",5,3) 

    Label("input_parent","curr_weight_label","curr_weight_input","Current Weight:"); 
    InputField("input_parent","curr_weight_input","text",5,3) 

    Label("input_parent","meals_label","meals_input","Daily Meals:"); 
    InputField("input_parent","meals_input","text",5,1) 

    Label("input_parent","goal_bf_pct_label","curr_weight_input","Current Weight:"); 
    InputField("input_parent","curr_weight_input","text",5,3) 

    Label("input_parent","time_label","time_input","Weeks To Goal:"); 
    InputField("input_parent","time_input","text",5,2) 

    Label("input_parent","deficit_label","deficit_select","Decifict By:"); 
    selectInputElement("input_child","deficit_select"); 
    selectOption("deficit_select","Please Select a deficit Method:", "none"); 
    selectOption("deficit_select","Burn With Exercise", "burn"); 
    selectOption("deficit_select","Fasting/Calorie Restriction Without Exercise", "starve"); 

結果是，儘管他們之前已經創建的標籤元素的兩個「選擇」的元素在最高層出現。

所以這最終渲染這樣的：

選擇元素

選擇元素

標籤< ---屬於第一選擇要素

標籤

inputfield

標籤

輸入字段

標籤

輸入字段

標籤

標籤< - 屬於第二輸入字段

它應該看起來更像這個（我加了空格來強調組織）：

標籤 選擇元素

標籤 inputfield

標籤 輸入字段

標籤 輸入字段

標籤 選擇元素

這裏是我的函數來創建這些元素：

function createDiv(section_id, div_id){ 
section=document.getElementById(section_id); 

div=document.createElement("div"); 
div.setAttribute("id",div_id); 

section.appendChild(div); 

} 

function selectInputElement(section_id,input_select_id){ 
section=document.getElementById(section_id); 

select_element=document.createElement("select"); 
select_element.setAttribute("id",input_select_id); 


section.appendChild(select_element); 
} 

function selectOption(input_select_id,option_text,option_value){ 
element=document.getElementById(input_select_id); 

option=document.createElement("OPTION"); 
text=document.createTextNode(option_text); 
option.setAttribute("value",option_value); 
option.appendChild(text); 

element.appendChild(option); 
} 


function InputField(section_id,input_id,element_type,size,length){ 

section=document.getElementById(section_id); 

input_field=document.createElement("input"); 
input_field.setAttribute("id",input_id); 
input_field.setAttribute("type",element_type); 
input_field.setAttribute("maxlength",size); 
input_field.setAttribute("size",length); 
section.appendChild(input_field); 

} 

function Label(section_id,label_id,label_for,label_text){ 
section=document.getElementById(section_id); 

label=document.createElement("label"); 
label.setAttribute("id",label_id); 
label.setAttribute("for",label_for); 
label_txt=document.createTextNode(label_text); 
label.appendChild(label_txt); 

section.appendChild(label); 
}

要追加的select元素比label（等）的元素不同的容器。

將它們全部附加到孩子使其按預期工作。

IMO，你的API將做好採取單個對象參數，所以你可以標值。
